Intermediate commit. Implement status variables to aid the DBA in determining the need and/or effectiveness of the per-engine mylsq.gtid_slave_pos feature: transactions_multi_engine Number of transactions that changed data in multiple (transactional) storage engines. rpl_transactions_multi_engine Number of replicated transactions that involved changes in multiple (transactional) storage engines, before considering the update of the mysql.gtid_slave_posXXX table. transactions_gtid_foreign_engine Number of replicated transactions where the update of the mysql.gtid_slave_posXXX table had to choose a storage engine that did not otherwise participate in the transaction.
