- regression got revealed while running tpcc workload. - as part of MDEV-25919 changes logic for statistics computation was revamped. - if the table has changed to certain threshold then table is added to statistics recomputation queue (dict_stats_recalc_pool_add) - after the table is added to queue the background statistics thread is notified - during revamp the condition to notify background statistics threads was wrongly updated to check if the queue/vector is empty when it should check if there is queue/vector has entries to process. - vec.begin() == vec.end() : only when vector is empty - also accessing these iterator outside the parallely changing vector is not safe - fix now tend to notify background statistics thread if the logic adds an entry to the queue/vector. |
