   Hi @pan3793 @cfmcgrady , I thought about this and still can't get the point why previously `multiple threads invoking SortBasedPusher#triggerPush simultaneously` will happen, could you explain it in more detail?
   According to https://docs.oracle.com/javase/tutorial/essential/concurrency/atomic.html cc @FMX , `volatile` guarantees atomicity and happens before, so IMO `volatile` is capable for the pushing logic.
