Kill Idle Transactions (mariadb &percona server 支持)

解决开发写SQL不commit 问题

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.

In Percona Server5.7.17-11 this feature has been re-implemented by setting a connection socket read timeout value instead of periodically scanning the internal InnoDB transaction list.

Version Specific Information

5.7.10-1:

Feature ported from Percona Server 5.6

5.7.17-11:

Feature re-implemented using socket timeouts
