INNODB_FT_DELETED table records rows that
are deleted from the
FULLTEXT index for an
InnoDB table. To avoid expensive index
reorganization during DML operations for an
FULLTEXT index, the
information about newly deleted words is stored separately,
filtered out of search results when you do a text search, and
removed from the main search index only when you issue the
OPTIMIZE TABLE statement for the
InnoDB table. See
Optimizing InnoDB Full-Text Indexes for more information.
This table initially appears empty, until you set the value of the
innodb_ft_aux_table to the name
(including the database name) of the table that contains the
FULLTEXT index, for example
For related usage information and examples, see Section 14.15.4, “InnoDB INFORMATION_SCHEMA FULLTEXT Index Tables”.
