step 1. Refresh process memory metrics. step 2. Refresh allocator memory metrics. step 3. Update and print memory stat when the memory changes by 256M. step 4. Asyn Refresh cache capacity step 5. Cancel top memory task when process memory exceed hard limit. step 6. Refresh weighted memory ratio of workload groups. step 7. Analyze blocking queries. step 8. Flush memtable. step 9. Jemalloc purge all arena dirty pages. `memory_maintenance_thread` execute once cost: - 3ms (cluster idle) - 20ms (cluster high concurrency, CPU full) `memory_maintenance_thread` CPU usage: - 10%-20% (default memory_maintenance_sleep_time_ms=20ms) - 20%-30% (memory_maintenance_sleep_time_ms=10ms) - 30%+ (memory_maintenance_sleep_time_ms=5ms) -- This is an automated message from the Apache Git Service.
