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 Server 5.6.35-80.0 this feature has been re-implemented by
setting a connection socket read timeout value instead of periodically scanning
the internal InnoDB transaction list.
5.6.11-60.3:- Feature ported from Percona Server 5.5
5.6.35-80.0:- Feature re-implemented using socket timeouts
