SHOW [FULL] PROCESSLIST

This statement lists the current sessions connected to the same TiDB server. The Info column contains the query text, which will be truncated unless the optional keyword FULL is specified. To view the processlist across the entire cluster, use the INFORMATION_SCHEMA.CLUSTER_PROCESSLIST table.

Synopsis

    "SHOW" "FULL"? "PROCESSLIST"

Examples

mysql> SHOW PROCESSLIST;
+------+------+-----------------+------+---------+------+------------+------------------+
| Id   | User | Host            | db   | Command | Time | State      | Info             |
+------+------+-----------------+------+---------+------+------------+------------------+

1 rows in set (0.00 sec)

Permissions

If the current user does not have the PROCESS privilege, SHOW PROCESSLIST only shows the requests from the user’s own sessions.

MySQL compatibility

• The State column in TiDB is non-descriptive. Representing state as a single value is more complex in TiDB, since queries are executed in parallel and each goroutine will have a different state at any one time.
