INNODB_FT_DELETED table stores
rows that are deleted from the
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 an
OPTIMIZE TABLE statement for the
InnoDB table. For more information, see
Optimizing InnoDB Full-Text Indexes.
This table is empty initially. Before querying it, set the value
variable to the name (including the database name) of the table
that contains the

The document ID of the newly deleted row. 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
InnoDBwhen the table contains no suitable column. This value is used when you perform text searches, to skip rows in the
INNODB_FT_INDEX_TABLEtable before data for deleted rows is physically removed from the
FULLTEXTindex by an
OPTIMIZE TABLEstatement. For more information, see Optimizing InnoDB Full-Text Indexes.
