Try to fix the race conditions between SET GLOBAL innodb_ft_aux_table = ...; and access to the INFORMATION_SCHEMA tables that depend on this variable. innodb_ft_aux_table: Replaces fts_internal_tbl_name,fts_internal_tbl_name2. Just store the user-specified parameter as is. innodb_ft_aux_table_id: The table_id corresponding to SET GLOBAL innodb_ft_aux_table, or 0 if the table does not exist or does not contain FULLTEXT INDEX. If the table is renamed later, the INFORMATION_SCHEMA tables will continue to refer to the table. If the table is dropped or rebuilt, the INFORMATION_SCHEMA tables will not find the table.
