### 26.4.15 The INFORMATION\_SCHEMA INNODB\_FT\_CONFIG Table

[]()

 The [`INNODB_FT_CONFIG`](information-schema-innodb-ft-config-table.html) table provides metadata about the `FULLTEXT` index and associated processing for an `InnoDB` table.

 This table is empty initially. Before querying it, set the value of the [`innodb_ft_aux_table`](innodb-parameters.html#sysvar_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`).

 For related usage information and examples, see [Section 15.15.4, “InnoDB INFORMATION\_SCHEMA FULLTEXT Index Tables”](innodb-information-schema-fulltext_index-tables.html).

 The [`INNODB_FT_CONFIG`](information-schema-innodb-ft-config-table.html) table has these columns:

* `KEY`

   The name designating an item of metadata for an `InnoDB` table containing a `FULLTEXT` index.

   The values for this column might change, depending on the needs for performance tuning and debugging for `InnoDB` full-text processing. The key names and their meanings include:

  * `optimize_checkpoint_limit`: The number of seconds after which an [`OPTIMIZE TABLE`](optimize-table.html) run stops.

  * `synced_doc_id`: The next `DOC_ID` to be issued.

  * `stopword_table_name`: The *`database/table`* name for a user-defined stopword table. The `VALUE` column is empty if there is no user-defined stopword table.

  * `use_stopword`: Indicates whether a stopword table is used, which is defined when the `FULLTEXT` index is created.

* `VALUE`

   The value associated with the corresponding `KEY` column, reflecting some limit or current value for an aspect of a `FULLTEXT` index for an `InnoDB` table.

#### Example

```
mysql> SELECT * FROM INFORMATION_SCHEMA.INNODB_FT_CONFIG;
+---------------------------+-------------------+
| KEY                       | VALUE             |
+---------------------------+-------------------+
| optimize_checkpoint_limit | 180               |
| synced_doc_id             | 0                 |
| stopword_table_name       | test/my_stopwords |
| use_stopword              | 1                 |
+---------------------------+-------------------+
```
