  • innodb_page_cleaners

  • innodb_purge_threads

  • innodb_read_io_threads

  • innodb_parallel_read_threads

  • innodb_redo_log_capacity (value set only if --innodb-dedicated-server is enabled.)

  • innodb_log_writer_threads

• The values of the following are calculated based on the available memory:

  • temptable_max_ram

  • innodb_buffer_pool_size (value set only if --innodb-dedicated-server is enabled.)
