Increased congestion on buf_pool.flush_list_mutex

    XMLWordPrintable

Details

    Description

      The buf_pool.flush_list_mutex became more contended after MDEV-27868 fixed a correctness issue that was caused by the performance fix MDEV-27774. We really should acquire and release buf_pool.flush_list_mutex at most once in mtr_t::commit() and reduce the amount of work performed while holding the mutex.
