Detect and terminate long-running queries

Aiven does not terminate any customer queries even if they run indefinitely, but long-running queries can cause issues by locking resources and therefore preventing database maintenance tasks such as backups.

To identify and terminate such long-running queries, you can do it from either:

Terminate long running queries from the Aiven Console​

  1. Log in to the Aiven Console.
  2. From the Services page, select your Aiven for MySQL® service.
  3. In your service's page, select Current queries from the sidebar.
  4. In the Current queries page, you can check the query duration and select Terminate to stop any long-running queries.

Detect and terminate long running queries via CLI​

You can login to your service using mysqlsh or mysql. Once connected, you can call the following command on the mysql shell to view all running queries:

SHOW PROCESSLIST WHERE command = 'Query' AND info NOT LIKE '%PROCESSLIST%';

You can learn more about the SHOW PROCESSLIST command from the official documentation.

You can terminate a query manually using:

KILL QUERY pid

where the pid is the process ID output by the SHOW PROCESSLIST command above.

You can learn more about the KILL QUERY command from the MySQL KILL documentation.
