The connector includes a number of performance improvements, detailed in the
following sections.

(mariadb-table-statistics)=
### Table statistics

The MariaDB connector can use [table and column
statistics](/optimizer/statistics) for [cost based
optimizations](/optimizer/cost-based-optimizations) to improve query processing
performance based on the actual data in the data source.

The statistics are collected by MariaDB and retrieved by the connector.

To collect statistics for a table, execute the following statement in
MariaDB.

```text
ANALYZE TABLE table_name;
```

Refer to [MariaDB documentation](https://mariadb.com/kb/en/analyze-table/) for
additional information.
