Provide some statistics about asynchronous IO reads and writes: - number of pending operations - number of completion callbacks that are currently being executed - number of completion callbacks that are currently queued (due to restriction on number of IO threads) - total number of IOs finished - total time to wait for free IO slot - total number of completions that were queued. Also revert tpool InnoDB perfschema instrumentation (MDEV-31048) That instrumentation of cache mutex did not bring any revelation ( the mutex is taken for a couple of instructions), and made it impossible to use tpool outside of the server (e.g in mariadbimport/dump) |
