LOAD STATS

The LOAD STATS statement is used to load the statistics into TiDB.

Note:

This feature is not available on TiDB Serverless clusters.

Synopsis

LoadStatsStmt ::=
    'LOAD' 'STATS' stringLit

Examples

You can access the address http://${tidb-server-ip}:${tidb-server-status-port}/stats/dump/${db_name}/${table_name} to download the TiDB instance's statistics.

You can also use LOAD STATS ${stats_path} to load the specific statistics file.

The ${stats_path} can be an absolute path or a relative path. If you use a relative path, the corresponding file is found starting from the path where tidb-server is started. Here is an example:

{{< copyable "sql" >}}

LOAD STATS '/tmp/stats.json';

Query OK, 0 rows affected (0.00 sec)

MySQL compatibility

This statement is a TiDB extension to MySQL syntax.
