 * Step1: Outside system execute ingestion etl job.
 * Step2: LoadEtlChecker will check ingestion etl job status periodically

 * Step3: LoadLoadingChecker will check loading status periodically and commit transaction when push tasks are finished.
 * Step4: PublishVersionDaemon will send publish version tasks to be and finish transaction.
