    Kill idle transactions¶

    This feature limits the age of idle transactions, for all transactional storage engines. If a transaction is idle for more seconds than the threshold specified, it will be killed. This prevents users from blocking InnoDB purge by mistake.

    Version specific information¶

    • 8.0.12-1: The feature was ported from Percona Server for MySQL 5.7.

    System variables¶

    kill_idle_transaction¶

    Option Description
    Config file Yes
    Scope: Global
    Dynamic: Yes
    Data type Integer
    Default value 0 (disabled)
    Units Seconds

    If non-zero, any idle transaction will be killed after being idle for this many seconds.
