Almost all threads have gone - the "ticking" threads, that sleep a while then do some work) (srv_monitor_thread, srv_error_monitor_thread, srv_master_thread) were replaced with timers. Some timers are periodic, e.g the "master" timer. - The btr_defragment_thread is also replaced by a timer , which reschedules it self when current defragment "item" needs throttling - the buf_resize_thread and buf_dump_threads are substitutes with tasks Ditto with page cleaner workers. - purge workers threads are not tasks as well, and purge cleaner coordinator is a combination of a task and timer. - All AIO is outsourced to tpool, Innodb just calls thread_pool::submit_io() and provides the callback. - The srv_slot_t was removed, and innodb_debug_sync used in purge is currently not working, and needs reimplementation.
