The mysqlpump client utility performs logical backups, producing a set of SQL statements that can be executed to reproduce the original database object definitions and table data. It dumps one or more MySQL databases for backup or transfer to another SQL server.
mysqlpump is deprecated as of MySQL 8.0.34 / 8.1.0; expect it to be removed in a future version of MySQL. You can use such MySQL programs as mysqldump and MySQL Shell to perform logical backups, dump databases, and similar tasks instead.
Consider using the MySQL Shell dump utilities, which provide parallel dumping with multiple threads, file compression, and progress information display, as well as cloud features such as Oracle Cloud Infrastructure Object Storage streaming, and MySQL HeatWave Service compatibility checks and modifications. Dumps can be easily imported into a MySQL Server instance or a MySQL HeatWave Service DB System using the MySQL Shell load dump utilities. Installation instructions for MySQL Shell can be found here.
mysqlpump features include:
-
Parallel processing of databases, and of objects within databases, to speed up the dump process
-
Better control over which databases and database objects (tables, stored programs, user accounts) to dump
-
Dumping of user accounts as account-management statements (
CREATE USER
,GRANT
) rather than as inserts into themysql
system database -
Capability of creating compressed output
-
Progress indicator (the values are estimates)
-
For dump file reloading, faster secondary index creation for
InnoDB
tables by adding indexes after rows are inserted
mysqlpump uses MySQL features introduced in MySQL 5.7, and thus assumes use with MySQL 5.7 or higher.
mysqlpump requires at least the SELECT
privilege for dumped tables, SHOW VIEW
for dumped views, TRIGGER
for dumped triggers, and LOCK TABLES
if the --single-transaction
option is not used. The SELECT
privilege on the mysql
system database is required to dump user definitions. Certain options might require other privileges as noted in the option descriptions.
To reload a dump file, you must have the privileges required to execute the statements that it contains, such as the appropriate CREATE
privileges for objects created by those statements.
A dump made using PowerShell on Windows with output redirection creates a file that has UTF-16 encoding:
mysqlpump [options] > dump.sql
However, UTF-16 is not permitted as a connection character set (see Section 12.4, “Connection Character Sets and Collations”), so the dump file cannot be loaded correctly. To work around this issue, use the --result-file
option, which creates the output in ASCII format:
mysqlpump [options] --result-file=dump.sql
mysqlpump Invocation Syntax
By default, mysqlpump dumps all databases (with certain exceptions noted in mysqlpump Restrictions). To specify this behavior explicitly, use the --all-databases
option:
mysqlpump --all-databases
To dump a single database, or certain tables within that database, name the database on the command line, optionally followed by table names:
mysqlpump db_name
mysqlpump db_name tbl_name1 tbl_name2 ...
To treat all name arguments as database names, use the --databases
option:
mysqlpump --databases db_name1 db_name2 ...
By default, mysqlpump does not dump user account definitions, even if you dump the mysql
system database that contains the grant tables. To dump grant table contents as logical definitions in the form of CREATE USER
and GRANT
statements, use the --users
option and suppress all database dumping:
mysqlpump --exclude-databases=% --users
In the preceding command, %
is a wildcard that matches all database names for the --exclude-databases
option.
mysqlpump supports several options for including or excluding databases, tables, stored programs, and user definitions. See mysqlpump Object Selection.
To reload a dump file, execute the statements that it contains. For example, use the mysql client:
mysqlpump [options] > dump.sql
mysql < dump.sql
The following discussion provides additional mysqlpump usage examples.
To see a list of the options mysqlpump supports, issue the command mysqlpump --help.
mysqlpump Option Summary
mysqlpump supports the following options, which can be specified on the command line or in the [mysqlpump]
and [client]
groups of an option file. mysqlpump also reads the [mysql_dump]
group but this behavior is deprecated. For information about option files used by MySQL programs, see Section 6.2.2.2, “Using Option Files”.

mysqlpump Option Descriptions
-
--help
,-?
Command-Line Format --help
Display a help message and exit.
-
Command-Line Format --add-drop-database
Write a
DROP DATABASE
statement before eachCREATE DATABASE
statement.NoteIn MySQL 8.3, the
mysql
schema is considered a system schema that cannot be dropped by end users. If--add-drop-database
is used with--all-databases
or with--databases
where the list of schemas to be dumped includesmysql
, the dump file contains aDROP DATABASE `mysql`
statement that causes an error when the dump file is reloaded.Instead, to use
--add-drop-database
, use--databases
with a list of schemas to be dumped, where the list does not includemysql
. -
Command-Line Format --add-drop-table
Write a
DROP TABLE
statement before eachCREATE TABLE
statement. -
Command-Line Format --add-drop-user
Write a
DROP USER
statement before eachCREATE USER
statement. -
Command-Line Format --add-locks
Surround each table dump with
LOCK TABLES
andUNLOCK TABLES
statements. This results in faster inserts when the dump file is reloaded. See Section 10.2.5.1, “Optimizing INSERT Statements”.This option does not work with parallelism because
INSERT
statements from different tables can be interleaved andUNLOCK TABLES
following the end of the inserts for one table could release locks on tables for which inserts remain.--add-locks
and--single-transaction
are mutually exclusive. -
--all-databases
,-A
Command-Line Format --all-databases
Dump all databases (with certain exceptions noted in mysqlpump Restrictions). This is the default behavior if no other is specified explicitly.
--all-databases
and--databases
are mutually exclusive.NoteSee the
--add-drop-database
description for information about an incompatibility of that option with--all-databases
.Prior to MySQL 8.3, the
--routines
and--events
options for mysqldump and mysqlpump were not required to include stored routines and events when using the--all-databases
option: The dump included themysql
system database, and therefore also themysql.proc
andmysql.event
tables containing stored routine and event definitions. As of MySQL 8.3, themysql.event
andmysql.proc
tables are not used. Definitions for the corresponding objects are stored in data dictionary tables, but those tables are not dumped. To include stored routines and events in a dump made using--all-databases
, use the--routines
and--events
options explicitly. -
Command-Line Format --bind-address=ip_address
On a computer having multiple network interfaces, use this option to select which interface to use for connecting to the MySQL server.
-
Command-Line Format --character-sets-dir=dir_name
Type Directory name The directory where character sets are installed. See Section 12.15, “Character Set Configuration”.
-
Command-Line Format --column-statistics
Type Boolean Default Value OFF
Add
ANALYZE TABLE
statements to the output to generate histogram statistics for dumped tables when the dump file is reloaded. This option is disabled by default because histogram generation for large tables can take a long time. -
Command-Line Format --complete-insert
Write complete
INSERT
statements that include column names. -
--compress
,-C
Command-Line Format --compress[={OFF|ON}]
Deprecated Yes Type Boolean Default Value OFF
Compress all information sent between the client and the server if possible. See Section 6.2.8, “Connection Compression Control”.
This option is deprecated. Expect it to be removed in a future version of MySQL. See Configuring Legacy Connection Compression.
-
Command-Line Format --compress-output=algorithm
Type Enumeration Valid Values LZ4
ZLIB
By default, mysqlpump does not compress output. This option specifies output compression using the specified algorithm. Permitted algorithms are
LZ4
andZLIB
.To uncompress compressed output, you must have an appropriate utility. If the system commands lz4 and openssl zlib are not available, MySQL distributions include lz4_decompress and zlib_decompress utilities that can be used to decompress mysqlpump output that was compressed using the
--compress-output=LZ4
and--compress-output=ZLIB
options. For more information, see Section 6.8.1, “lz4_decompress — Decompress mysqlpump LZ4-Compressed Output”, and Section 6.8.3, “zlib_decompress — Decompress mysqlpump ZLIB-Compressed Output”. -
--compression-algorithms=
value
Command-Line Format --compression-algorithms=value
Type Set Default Value uncompressed
Valid Values zlib
zstd
uncompressed
The permitted compression algorithms for connections to the server. The available algorithms are the same as for the
protocol_compression_algorithms
system variable. The default value isuncompressed
.For more information, see Section 6.2.8, “Connection Compression Control”.
-
--databases
,-B
Command-Line Format --databases
Normally, mysqlpump treats the first name argument on the command line as a database name and any following names as table names. With this option, it treats all name arguments as database names.
CREATE DATABASE
statements are included in the output before each new database.--all-databases
and--databases
are mutually exclusive.NoteSee the
--add-drop-database
description for information about an incompatibility of that option with--databases
. -
--debug[=
,debug_options
]-# [
debug_options
]Command-Line Format --debug[=debug_options]
Type String Default Value d:t:O,/tmp/mysqlpump.trace
Write a debugging log. A typical
debug_options
string isd:t:o,
. The default isfile_name
d:t:O,/tmp/mysqlpump.trace
.This option is available only if MySQL was built using
WITH_DEBUG
. MySQL release binaries provided by Oracle are not built using this option. -
Command-Line Format --debug-check
Type Boolean Default Value FALSE
Print some debugging information when the program exits.
This option is available only if MySQL was built using
WITH_DEBUG
. MySQL release binaries provided by Oracle are not built using this option. -
--debug-info
,-T
Command-Line Format --debug-info
Type Boolean Default Value FALSE
Print debugging information and memory and CPU usage statistics when the program exits.
This option is available only if MySQL was built using
WITH_DEBUG
. MySQL release binaries provided by Oracle are not built using this option. -
Command-Line Format --default-auth=plugin
Type String A hint about which client-side authentication plugin to use. See Section 8.2.17, “Pluggable Authentication”.
-
--default-character-set=
charset_name
Command-Line Format --default-character-set=charset_name
Type String Default Value utf8
Use
charset_name
as the default character set. See Section 12.15, “Character Set Configuration”. If no character set is specified, mysqlpump usesutf8mb4
. -
Command-Line Format --default-parallelism=N
Type Integer Default Value 2
The default number of threads for each parallel processing queue. The default is 2.
The
--parallel-schemas
option also affects parallelism and can be used to override the default number of threads. For more information, see mysqlpump Parallel Processing.With
--default-parallelism=0
and no--parallel-schemas
options, mysqlpump runs as a single-threaded process and creates no queues.With parallelism enabled, it is possible for output from different databases to be interleaved.
-
--defaults-extra-file=
file_name
Command-Line Format --defaults-extra-file=file_name
Type File name Read this option file after the global option file but (on Unix) before the user option file. If the file does not exist or is otherwise inaccessible, an error occurs. If
file_name
is not an absolute path name, it is interpreted relative to the current directory.For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
-
Command-Line Format --defaults-file=file_name
Type File name Use only the given option file. If the file does not exist or is otherwise inaccessible, an error occurs. If
file_name
is not an absolute path name, it is interpreted relative to the current directory.Exception: Even with
--defaults-file
, client programs read.mylogin.cnf
.For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
-
Command-Line Format --defaults-group-suffix=str
Type String Read not only the usual option groups, but also groups with the usual names and a suffix of
str
. For example, mysqlpump normally reads the[client]
and[mysqlpump]
groups. If this option is given as--defaults-group-suffix=_other
, mysqlpump also reads the[client_other]
and[mysqlpump_other]
groups.For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
-
Command-Line Format --defer-table-indexes
Type Boolean Default Value TRUE
In the dump output, defer index creation for each table until after its rows have been loaded. This works for all storage engines, but for
InnoDB
applies only for secondary indexes.This option is enabled by default; use
--skip-defer-table-indexes
to disable it. -
Command-Line Format --events
Type Boolean Default Value TRUE
Include Event Scheduler events for the dumped databases in the output. Event dumping requires the
EVENT
privileges for those databases.The output generated by using
--events
containsCREATE EVENT
statements to create the events.This option is enabled by default; use
--skip-events
to disable it. -
Command-Line Format --exclude-databases=db_list
Type String Do not dump the databases in
db_list
, which is a list of one or more comma-separated database names. Multiple instances of this option are additive. For more information, see mysqlpump Object Selection. -
Command-Line Format --exclude-events=event_list
Type String Do not dump the databases in
event_list
, which is a list of one or more comma-separated event names. Multiple instances of this option are additive. For more information, see mysqlpump Object Selection. -
--exclude-routines=

trigger_list
, which is a list of one or more comma-separated trigger names. Multiple instances of this option are additive. For more information, see mysqlpump Object Selection. -
Command-Line Format --exclude-users=user_list
Type String Do not dump the user accounts in
user_list
, which is a list of one or more comma-separated account names. Multiple instances of this option are additive. For more information, see mysqlpump Object Selection. -
Command-Line Format --extended-insert=N
Write
INSERT
statements using multiple-row syntax that includes severalVALUES
lists. This results in a smaller dump file and speeds up inserts when the file is reloaded.The option value indicates the number of rows to include in each
INSERT
statement. The default is 250. A value of 1 produces oneINSERT
statement per table row. -
Command-Line Format --get-server-public-key
Type Boolean Request from the server the public key required for RSA key pair-based password exchange. This option applies to clients that authenticate with the
caching_sha2_password
authentication plugin. For that plugin, the server does not send the public key unless requested. This option is ignored for accounts that do not authenticate with that plugin. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection.If
--server-public-key-path=
is given and specifies a valid public key file, it takes precedence overfile_name
--get-server-public-key
.For information about the
caching_sha2_password
plugin, see Section 8.4.1.2, “Caching SHA-2 Pluggable Authentication”. -
Command-Line Format --hex-blob
Dump binary columns using hexadecimal notation (for example,
'abc'
becomes0x616263
). The affected data types areBINARY
,VARBINARY
,BLOB
types,BIT
, all spatial data types, and other non-binary data types when used with thebinary
character set. -
--host=

Command-Line Format --include-events=event_list
Type String Dump the events in
event_list
, which is a list of one or more comma-separated event names. Multiple instances of this option are additive. For more information, see mysqlpump Object Selection. -
--include-routines=
routine_list
Command-Line Format --include-routines=routine_list
Type String Dump the routines in
routine_list
, which is a list of one or more comma-separated routine (stored procedure or function) names. Multiple instances of this option are additive. For more information, see mysqlpump Object Selection. -
Command-Line Format --include-tables=table_list
Type String Dump the tables in
table_list
, which is a list of one or more comma-separated table names. Multiple instances of this option are additive. For more information, see mysqlpump Object Selection. -

Write
INSERT IGNORE
statements rather thanINSERT
statements. -
Command-Line Format --log-error-file=file_name
Type File name Log warnings and errors by appending them to the named file. If this option is not given, mysqlpump writes warnings and errors to the standard error output.
-
Command-Line Format --login-path=name
Type String Read options from the named login path in the
.mylogin.cnf
login path file. A “login path” is an option group containing options that specify which MySQL server to connect to and which account to authenticate as. To create or modify a login path file, use the mysql_config_editor utility. See Section 6.6.7, “mysql_config_editor — MySQL Configuration Utility”.For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
-
Command-Line Format --no-login-paths
Skips reading options from the login path file.
See
--login-path
for related information.For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
-
Command-Line Format --max-allowed-packet=N

The maximum size of the buffer for client/server communication. The default is 24MB, the maximum is 1GB.
-
Command-Line Format --net-buffer-length=N
Type Numeric Default Value 1047552
The initial size of the buffer for client/server communication. When creating multiple-row
INSERT
statements (as with the--extended-insert
option), mysqlpump creates rows up toN
bytes long. If you use this option to increase the value, ensure that the MySQL servernet_buffer_length
system variable has a value at least this large. -
Command-Line Format --no-create-db
Suppress any
CREATE DATABASE
statements that might otherwise be included in the output. -
--no-create-info
,-t
Command-Line Format --no-create-info
Do not write
CREATE TABLE
statements that create each dumped table. -
Command-Line Format --no-defaults
Do not read any option files. If program startup fails due to reading unknown options from an option file,
--no-defaults
can be used to prevent them from being read.The exception is that the
.mylogin.cnf
file is read in all cases, if it exists. This permits passwords to be specified in a safer way than on the command line even when--no-defaults
is used. To create.mylogin.cnf
, use the mysql_config_editor utility. See Section 6.6.7, “mysql_config_editor — MySQL Configuration Utility”.For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
-
--parallel-schemas=[
N
:]db_list
Command-Line Format --parallel-schemas=[N:]schema_list
Type String Create a queue for processing the databases in
db_list
, which is a list of one or more comma-separated database names. IfN
is given, the queue usesN
threads. IfN
is not given, the--default-parallelism
option determines the number of queue threads.Multiple instances of this option create multiple queues. mysqlpump also creates a default queue to use for databases not named in any
--parallel-schemas
option, and for dumping user definitions if command options select them. For more information, see mysqlpump Parallel Processing. -
--password[=
,password
]-p[
password
]Command-Line Format --password[=password]
Type String The password of the MySQL account used for connecting to the server. The password value is optional. If not given, mysqlpump prompts for one. If given, there must be no space between
--password=
or-p
and the password following it. If no password option is specified, the default is to send no password.Specifying a password on the command line should be considered insecure. To avoid giving the password on the command line, use an option file. See Section 8.1.2.1, “End-User Guidelines for Password Security”.
To explicitly specify that there is no password and that mysqlpump should not prompt for one, use the
--skip-password
option. -
The password for multifactor authentication factor 1 of the MySQL account used for connecting to the server. The password value is optional. If not given, mysqlpump prompts for one. If given, there must be no space between
--password1=
and the password following it. If no password option is specified, the default is to send no password.Specifying a password on the command line should be considered insecure. To avoid giving the password on the command line, use an option file. See Section 8.1.2.1, “End-User Guidelines for Password Security”.
To explicitly specify that there is no password and that mysqlpump should not prompt for one, use the
--skip-password1
option.--password1
and--password
are synonymous, as are--skip-password1
and--skip-password
. -
The password for multifactor authentication factor 2 of the MySQL account used for connecting to the server. The semantics of this option are similar to the semantics for
--password1
; see the description of that option for details. -
The password for multifactor authentication factor 3 of the MySQL account used for connecting to the server. The semantics of this option are similar to the semantics for
--password1
; see the description of that option for details. -
Command-Line Format --plugin-dir=dir_name
Type Directory name The directory in which to look for plugins. Specify this option if the
--default-auth
option is used to specify an authentication plugin but mysqlpump does not find it. See Section 8.2.17, “Pluggable Authentication”. -

-P
port_num
Command-Line Format --port=port_num
Type Numeric Default Value 3306
For TCP/IP connections, the port number to use.
-
Command-Line Format --print-defaults
Print the program name and all options that it gets from option files.
For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
-
--protocol={TCP|SOCKET|PIPE|MEMORY}
Command-Line Format --protocol=type
Type String Default Value [see text]
Valid Values TCP
SOCKET
PIPE
MEMORY
The transport protocol to use for connecting to the server. It is useful when the other connection parameters normally result in use of a protocol other than the one you want. For details on the permissible values, see Section 6.2.7, “Connection Transport Protocols”.
-
Command-Line Format --replace
-
Command-Line Format --result-file=file_name
Type File name Direct output to the named file. The result file is created and its previous contents overwritten, even if an error occurs while generating the dump.
This option should be used on Windows to prevent newline
\n
characters from being converted to\r\n
carriage return/newline sequences. -
Command-Line Format --routines
Type Boolean Default Value TRUE
Include stored routines (procedures and functions) for the dumped databases in the output. This option requires the global
SELECT
privilege.The output generated by using
--routines
containsCREATE PROCEDURE
andCREATE FUNCTION
statements to create the routines.This option is enabled by default; use
--skip-routines
to disable it. -
--server-public-key-path=
file_name
Command-Line Format --server-public-key-path=file_name
Type File name The path name to a file in PEM format containing a client-side copy of the public key required by the server for RSA key pair-based password exchange. This option applies to clients that authenticate with the
sha256_password
orcaching_sha2_password
authentication plugin. This option is ignored for accounts that do not authenticate with one of those plugins. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection.If
--server-public-key-path=
is given and specifies a valid public key file, it takes precedence overfile_name
--get-server-public-key
.For
sha256_password
, this option applies only if MySQL was built using OpenSSL.For information about the
sha256_password
andcaching_sha2_password
plugins, see Section 8.4.1.3, “SHA-256 Pluggable Authentication”, and Section 8.4.1.2, “Caching SHA-2 Pluggable Authentication”. -
Command-Line Format --set-charset
Write
SET NAMES
to the output.default_character_set
This option is enabled by default. To disable it and suppress the
SET NAMES
statement, use--skip-set-charset
. -
Command-Line Format --set-gtid-purged=value
Type Enumeration Default Value AUTO
Valid Values OFF
ON
AUTO
This option enables control over global transaction ID (GTID) information written to the dump file, by indicating whether to add a
SET @@GLOBAL.gtid_purged
statement to the output. This option may also cause a statement to be written to the output that disables binary logging while the dump file is being reloaded.The following table shows the permitted option values. The default value is
AUTO
.Value Meaning OFF
Add no SET
statement to the output.ON
Add a SET
statement to the output. An error occurs if GTIDs are not enabled on the server.AUTO
Add a SET
statement to the output if GTIDs are enabled on the server.The
--set-gtid-purged
option has the following effect on binary logging when the dump file is reloaded:-
--set-gtid-purged=OFF
:SET @@SESSION.SQL_LOG_BIN=0;
is not added to the output. -
--set-gtid-purged=ON
:SET @@SESSION.SQL_LOG_BIN=0;
is added to the output. -
--set-gtid-purged=AUTO
:SET @@SESSION.SQL_LOG_BIN=0;
is added to the output if GTIDs are enabled on the server you are backing up (that is, ifAUTO
evaluates toON
).

-
Command-Line Format --single-transaction
This option sets the transaction isolation mode to
REPEATABLE READ
and sends aSTART TRANSACTION
SQL statement to the server before dumping data. It is useful only with transactional tables such asInnoDB
, because then it dumps the consistent state of the database at the time whenSTART TRANSACTION
was issued without blocking any applications.When using this option, you should keep in mind that only
InnoDB
tables are dumped in a consistent state. For example, anyMyISAM
orMEMORY
tables dumped while using this option may still change state.While a
--single-transaction
dump is in process, to ensure a valid dump file (correct table contents and binary log coordinates), no other connection should use the following statements:ALTER TABLE
,CREATE TABLE
,DROP TABLE
,RENAME TABLE
,TRUNCATE TABLE
. A consistent read is not isolated from those statements, so use of them on a table to be dumped can cause theSELECT
that is performed by mysqlpump to retrieve the table contents to obtain incorrect contents or fail.--add-locks
and--single-transaction
are mutually exclusive. -
Command-Line Format --skip-definer
Type Boolean Default Value FALSE
Omit
DEFINER
andSQL SECURITY
clauses from theCREATE
statements for views and stored programs. The dump file, when reloaded, creates objects that use the defaultDEFINER
andSQL SECURITY
values. See Section 27.6, “Stored Object Access Control”. -
--skip-dump-rows
,-d
Command-Line Format --skip-dump-rows
Type Boolean Default Value FALSE
Do not dump table rows.
-
--skip-generated-invisible-primary-key
Command-Line Format --skip-generated-invisible-primary-key
Type Boolean Default Value FALSE
This option causes generated invisible primary keys (GIPKs) to be excluded from the dump. See Section 15.1.20.11, “Generated Invisible Primary Keys”, for more information about GIPKs and GIPK mode.
-
--socket=
,path
-S
path
Command-Line Format --socket={file_name|pipe_name}
Type String For connections to
localhost
, the Unix socket file to use, or, on Windows, the name of the named pipe to use.On Windows, this option applies only if the server was started with the
named_pipe
system variable enabled to support named-pipe connections. In addition, the user making the connection must be a member of the Windows group specified by thenamed_pipe_full_access_group
system variable. -
Options that begin with
--ssl
specify whether to connect to the server using encryption and indicate where to find SSL keys and certificates. See Command Options for Encrypted Connections. -
--ssl-fips-mode={OFF|ON|STRICT}
Command-Line Format --ssl-fips-mode={OFF|ON|STRICT}
Deprecated Yes Type Enumeration Default Value OFF
Valid Values OFF
ON
STRICT
Controls whether to enable FIPS mode on the client side. The
--ssl-fips-mode
option differs from other--ssl-
options in that it is not used to establish encrypted connections, but rather to affect which cryptographic operations to permit. See Section 8.8, “FIPS Support”.xxx
These
--ssl-fips-mode
values are permitted:-
OFF
: Disable FIPS mode. -
ON
: Enable FIPS mode. -
STRICT
: Enable “strict” FIPS mode.
NoteIf the OpenSSL FIPS Object Module is not available, the only permitted value for
--ssl-fips-mode
isOFF
. In this case, setting--ssl-fips-mode
toON
orSTRICT
causes the client to produce a warning at startup and to operate in non-FIPS mode.This option is deprecated. Expect it to be removed in a future version of MySQL.

--tls-ciphersuites=
ciphersuite_list
Command-Line Format --tls-ciphersuites=ciphersuite_list
Type String The permissible ciphersuites for encrypted connections that use TLSv1.3. The value is a list of one or more colon-separated ciphersuite names. The ciphersuites that can be named for this option depend on the SSL library used to compile MySQL. For details, see Section 8.3.2, “Encrypted Connection TLS Protocols and Ciphers”.
-
--tls-sni-servername=
server_name
Command-Line Format --tls-sni-servername=server_name
Type String When specified, the name is passed to the
libmysqlclient
C API library using theMYSQL_OPT_TLS_SNI_SERVERNAME
option ofmysql_options()
. The server name is not case-sensitive. To show which server name the client specified for the current session, if any, check theTls_sni_server_name
status variable.Server Name Indication (SNI) is an extension to the TLS protocol (OpenSSL must be compiled using TLS extensions for this option to function). The MySQL implementation of SNI represents the client-side only.
-
Command-Line Format --tls-version=protocol_list
Type String Default Value TLSv1,TLSv1.1,TLSv1.2,TLSv1.3
(OpenSSL 1.1.1 or higher)TLSv1,TLSv1.1,TLSv1.2
(otherwise)The permissible TLS protocols for encrypted connections. The value is a list of one or more comma-separated protocol names. The protocols that can be named for this option depend on the SSL library used to compile MySQL. For details, see Section 8.3.2, “Encrypted Connection TLS Protocols and Ciphers”.
-
Command-Line Format --triggers
Type Boolean Default Value TRUE
Include triggers for each dumped table in the output.
This option is enabled by default; use
--skip-triggers
to disable it. -
Command-Line Format --tz-utc
This option enables
TIMESTAMP
columns to be dumped and reloaded between servers in different time zones. mysqlpump sets its connection time zone to UTC and addsSET TIME_ZONE='+00:00'
to the dump file. Without this option,TIMESTAMP
columns are dumped and reloaded in the time zones local to the source and destination servers, which can cause the values to change if the servers are in different time zones.--tz-utc
also protects against changes due to daylight saving time.This option is enabled by default; use
--skip-tz-utc
to disable it. -
--user=
,user_name
-u
user_name
Command-Line Format --user=user_name
Type String The user name of the MySQL account to use for connecting to the server.
If you are using the
Rewriter
plugin, you should grant this user theSKIP_QUERY_REWRITE
privilege. -
Command-Line Format --users
Type Boolean Default Value FALSE
Dump user accounts as logical definitions in the form of
CREATE USER
andGRANT
statements.User definitions are stored in the grant tables in the
mysql
system database. By default, mysqlpump does not include the grant tables inmysql
database dumps. To dump the contents of the grant tables as logical definitions, use the--users
option and suppress all database dumping:mysqlpump --exclude-databases=% --users
-
--version
,-V
Command-Line Format --version
Display version information and exit.
-
Command-Line Format --watch-progress
Type Boolean Default Value TRUE
Periodically display a progress indicator that provides information about the completed and total number of tables, rows, and other objects.
This option is enabled by default; use
--skip-watch-progress
to disable it. -
--zstd-compression-level=
level
Command-Line Format --zstd-compression-level=#
Type Integer The compression level to use for connections to the server that use the
zstd
compression algorithm. The permitted levels are from 1 to 22, with larger values indicating increasing levels of compression. The defaultzstd
compression level is 3. The compression level setting has no effect on connections that do not usezstd
compression.For more information, see Section 6.2.8, “Connection Compression Control”.
mysqlpump Object Selection
mysqlpump has a set of inclusion and exclusion options that enable filtering of several object types and provide flexible control over which objects to dump:
-
--include-databases
and--exclude-databases
apply to databases and all objects within them. -
--include-tables
and--exclude-tables
apply to tables. These options also affect triggers associated with tables unless the trigger-specific options are given. -
--include-triggers
and--exclude-triggers
apply to triggers. -
--include-routines
and--exclude-routines
apply to stored procedures and functions. If a routine option matches a stored procedure name, it also matches a stored function of the same name. -
--include-events
and--exclude-events
apply to Event Scheduler events. -
--include-users
and--exclude-users
apply to user accounts.
Any inclusion or exclusion option may be given multiple times. The effect is additive. Order of these options does not matter.
The value of each inclusion and exclusion option is a list of comma-separated names of the appropriate object type. For example:
--exclude-databases=test,world
--include-tables=customer,invoice
Wildcard characters are permitted in the object names:
-
%
matches any sequence of zero or more characters. -
_
matches any single character.
For example, --include-tables=t%,__tmp
matches all table names that begin with t
and all five-character table names that end with tmp
.
For users, a name specified without a host part is interpreted with an implied host of %
. For example, u1
and u1@%
are equivalent. This is the same equivalence that applies in MySQL generally (see Section 8.2.4, “Specifying Account Names”).
Inclusion and exclusion options interact as follows:
-
By default, with no inclusion or exclusion options, mysqlpump dumps all databases (with certain exceptions noted in mysqlpump Restrictions).
-
If inclusion options are given in the absence of exclusion options, only the objects named as included are dumped.
-
If exclusion options are given in the absence of inclusion options, all objects are dumped except those named as excluded.
-
If inclusion and exclusion options are given, all objects named as excluded and not named as included are not dumped. All other objects are dumped.
If multiple databases are being dumped, it is possible to name tables, triggers, and routines in a specific database by qualifying the object names with the database name. The following command dumps databases db1
and db2
, but excludes tables db1.t1
and db2.t2
:
mysqlpump --include-databases=db1,db2 --exclude-tables=db1.t1,db2.t2
The following options provide alternative ways to specify which databases to dump:
-
The
--all-databases
option dumps all databases (with certain exceptions noted in mysqlpump Restrictions). It is equivalent to specifying no object options at all (the default mysqlpump action is to dump everything).--include-databases=%
is similar to--all-databases
, but selects all databases for dumping, even those that are exceptions for--all-databases
. -
The
--databases
option causes mysqlpump to treat all name arguments as names of databases to dump. It is equivalent to an--include-databases
option that names the same databases.
mysqlpump Parallel Processing
mysqlpump can use parallelism to achieve concurrent processing. You can select concurrency between databases (to dump multiple databases simultaneously) and within databases (to dump multiple objects from a given database simultaneously).
By default, mysqlpump sets up one queue with two threads. You can create additional queues and control the number of threads assigned to each one, including the default queue:
-
--default-parallelism=
specifies the default number of threads used for each queue. In the absence of this option,N
N
is 2.The default queue always uses the default number of threads. Additional queues use the default number of threads unless you specify otherwise.
-
--parallel-schemas=[
sets up a processing queue for dumping the databases named inN
:]db_list
db_list
and optionally specifies how many threads the queue uses.db_list
is a list of comma-separated database names. If the option argument begins with
, the queue usesN
:N
threads. Otherwise, the--default-parallelism
option determines the number of queue threads.Multiple instances of the
--parallel-schemas
option create multiple queues.Names in the database list are permitted to contain the same
%
and_
wildcard characters supported for filtering options (see mysqlpump Object Selection).
mysqlpump uses the default queue for processing any databases not named explicitly with a --parallel-schemas
option, and for dumping user definitions if command options select them.
In general, with multiple queues, mysqlpump uses parallelism between the sets of databases processed by the queues, to dump multiple databases simultaneously. For a queue that uses multiple threads, mysqlpump uses parallelism within databases, to dump multiple objects from a given database simultaneously. Exceptions can occur; for example, mysqlpump may block queues while it obtains from the server lists of objects in databases.
With parallelism enabled, it is possible for output from different databases to be interleaved. For example, INSERT
statements from multiple tables dumped in parallel can be interleaved; the statements are not written in any particular order. This does not affect reloading because output statements qualify object names with database names or are preceded by USE
statements as required.
The granularity for parallelism is a single database object. For example, a single table cannot be dumped in parallel using multiple threads.
Examples:
mysqlpump --parallel-schemas=db1,db2 --parallel-schemas=db3
mysqlpump sets up a queue to process db1
and db2
, another queue to process db3
, and a default queue to process all other databases. All queues use two threads.
mysqlpump --parallel-schemas=db1,db2 --parallel-schemas=db3
--default-parallelism=4
This is the same as the previous example except that all queues use four threads.
mysqlpump --parallel-schemas=5:db1,db2 --parallel-schemas=3:db3
The queue for db1
and db2
uses five threads, the queue for db3
uses three threads, and the default queue uses the default of two threads.
As a special case, with --default-parallelism=0
and no --parallel-schemas
options, mysqlpump runs as a single-threaded process and creates no queues.
mysqlpump Restrictions
mysqlpump does not dump the performance_schema
, ndbinfo
, or sys
schema by default. To dump any of these, name them explicitly on the command line. You can also name them with the --databases
or --include-databases
option.
mysqlpump does not dump the INFORMATION_SCHEMA
schema.
mysqlpump does not dump InnoDB
CREATE TABLESPACE
statements.
mysqlpump dumps user accounts in logical form using CREATE USER
and GRANT
statements (for example, when you use the --include-users
or --users
option). For this reason, dumps of the mysql
system database do not by default include the grant tables that contain user definitions: user
, db
, tables_priv
, columns_priv
, procs_priv
, or proxies_priv
. To dump any of the grant tables, name the mysql
database followed by the table names:
mysqlpump mysql user db ...
