+VARIABLE_COMMENT Normally does not need tuning. How many old rows must accumulate in the mysql.gtid_slave_pos table before a background job will be run to delete them. Can be increased to reduce number of commits if using many different engines with --gtid_pos_auto_engines, or to reduce CPU overhead if using a huge number of different gtid_domain_ids. Can be decreased to reduce number of old rows in the table.
