   For `CrossSpaceCompactionWriter`, multiple threads may write to multiple different `TsFileIOWriter`, if we synchronized them with a single object, it may lead to performance decrease. It's better to maintain a global array, which map sub-task-id to the writer they are using. When thread writes data, it only needs to synchronized the writer it is using.
