Make innodb_purge_threads settable without server restart

    XMLWordPrintable

Details

    Description

      To enable better control of the InnoDB purge subsystem, it would be good if the maximum number of purge tasks were settable by the user while the server is running:

      SET GLOBAL innodb_purge_threads=1;
      		 
      # run a heavy workload
      		 
      # let the history be discarded faster while the server is less busy
      		 
      SET GLOBAL innodb_purge_threads=32;

      Independently of this, MDEV-16260 or MDEV-26356 may improve the way how the purge threads are scheduled. This task would only make the maximum number of concurrent purge tasks configurable.
