The INNODB_FT_BEING_DELETED
table provides a snapshot of the INNODB_FT_DELETED
table; it is used only during an OPTIMIZE TABLE
maintenance operation. When OPTIMIZE TABLE
is run, the INNODB_FT_BEING_DELETED
table is emptied, and DOC_ID
values are removed from the INNODB_FT_DELETED
table. Because the contents of INNODB_FT_BEING_DELETED
typically have a short lifetime, this table has limited utility for monitoring or debugging. For information about running OPTIMIZE TABLE
on tables with FULLTEXT
indexes, see Section 14.9.6, “Fine-Tuning MySQL Full-Text Search”.
This table is empty initially. Before querying it, set the value of the innodb_ft_aux_table
system variable to the name (including the database name) of the table that contains the FULLTEXT
index (for example, test/articles
). The output appears similar to the example provided for the INNODB_FT_DELETED
table.
For related usage information and examples, see Section 17.15.4, “InnoDB INFORMATION_SCHEMA FULLTEXT Index Tables”.
The INNODB_FT_BEING_DELETED
table has these columns:
-
DOC_ID
The document ID of the row that is in the process of being deleted. This value might reflect the value of an ID column that you defined for the underlying table, or it can be a sequence value generated by
InnoDB
when the table contains no suitable column. This value is used when you perform text searches, to skip rows in theINNODB_FT_INDEX_TABLE
table before data for deleted rows is physically removed from theFULLTEXT
index by anOPTIMIZE TABLE
statement. For more information, see Optimizing InnoDB Full-Text Indexes.
