* Add stats and counter around cost model ops, mainly: - calculate transaction cost - check transaction can fit in a block - update block cost tracker after transactions are added to block - replay_stage to update/insert execution cost to table * Change mutex on cost_tracker to RwLock * removed cloning cost_tracker for local use, as the metrics show clone is very expensive. * acquire and hold locks for block of TXs, instead of acquire and release per transaction; * remove redundant would_fit check from cost_tracker update execution path * refactor cost checking with less frequent lock acquiring * avoid many Transaction_cost heap allocation when calculate cost, which is in the hot path - executed per transaction. * create hashmap with new_capacity to reduce runtime heap realloc. * code review changes: categorize stats, replace explicit drop calls, concisely initiate to default * address potential deadlock by acquiring locks one at time |
