…action score and workload (apache#36672) 1 Resolved the issue where the priority queue did not reserve slots for cumulative compaction. 2 When considering compaction task priorities, introduced metrics for CPU and memory usage rates. When the compaction score is low, and CPU or memory usage is high, reduce the number of compaction tasks generated and allocate CPU and memory resources to queries or load. 3 Integrated the logic of the priority queue and concurrency control together, removing the previous priority code.
…pache#37171) 1 When enable_system_metrics = false, system_metrics is a null pointer 2 When BE exits, system_metrics has been destructed, and the compaction background thread may still be running
