Creating numerous tables, each with a  FULLTEXT  search index, could consume a significant portion of available memory.  innodb_ft_total_cache_size  defines a global memory limit for all full-text search indexes to help avoid excessive memory consumption. If the global limit is reached by an index operation, a forced sync is triggered. For more information, see InnoDB Full-Text Index Cache. This option is used to specify your own  InnoDB FULLTEXT  index stopword list on a specific table. To configure your own stopword list for all  InnoDB  tables, use  innodb_ft_server_stopword_table . Set  innodb_ft_user_stopword_table  to the name of the table containing a list of stopwords, in the format  db_name / table_name . The stopword table must exist before you configure  innodb_ft_user_stopword_table . innodb_ft_enable_stopword  must be enabled and  innodb_ft_user_stopword_table  must be configured before you create the  FULLTEXT  index. The stopword table must be an  InnoDB  table, containing a single  VARCHAR  column named  value . For more information, see Section 12.10.4, “Full-Text Stopwords” . • innodb_ft_user_stopword_table • innodb_idle_flush_pct 3254 Command-Line Format --innodb-ft-user-stopword- table=db_name/table_name System Variable innodb_ft_user_stopword_table Scope Global, Session Dynamic Yes SET_VAR  Hint Applies No Type String Default Value NULL Command-Line Format --innodb-idle-flush-pct=# Introduced 8.0.18 System Variable innodb_idle_flush_pct Scope Global Dynamic Yes SET_VAR  Hint Applies No
