      Description

      We noticed some performance degradation in our product when we replaced the MySQL Connector/J client with MariaDB Java client and were able to trace the performance decrease back to the large number of 'get @@autocommit' and 'set autocommit' queries sent to the database.

      Instead of sending these queries to the databse each time getAutocommit() and setAutocommit() are called, the autocommit value may be cached on a per connection basis to improve performance.
