PROGRESS NOTES:



DESCRIPTION:

The MWL#116 implements group commit for the binary log.

The work in MWL#116 only facilitates group commit for transactional commit
events. Non-transactional events like DDL or updates to MyISAM tables are not
improved. This is mainly an issue when running with sync_binlog=1

This worklog is for extending the optimisation to also do group commit for
these non-transactional event writes.

The basic way to implement this is described in the low-level design of
MWL#116, section 2.3.
