Add optional purge and write back for MariaDB TPROC-C #642

Closed sm-shaw closed 7 months ago

sm-shaw commented 8 months ago

Only compatible with MariaDB 10.7.1 and above where purge_threads are dynamic. Functionality is not possible to add to MySQL at the present time as innodb_purge_threads is a read only variable and functionality is dependent on setting purge_threads temporarily to a high value to accelerate the purge process.

In the CLI the time for purge and write back with require a higher setting of keepalive_time. Plan to add a gdset command to set generic dict settings dynamically rather than only through XML to achieve this.

Tested for both sync and async options

Merging after reviews and approval of the three members of the code maintenance team.
