> Key: HUDI-415
> URL: https://issues.apache.org/jira/browse/HUDI-415
> Project: Apache Hudi (incubating)
> Issue Type: Bug
> Reporter: Yanjia Gary Li

> Hudi records the commit time after the first action complete. If there is a heavy transformation before isEmpty(), then the commit time could be inaccurate.
> {code:java}
> if (hoodieRecords.isEmpty()) {
> log.info("new batch has no new records, skipping...")
> return (true, common.util.Option.empty())
> }
> commitTime = client.startCommit()
> writeStatuses = DataSourceUtils.doWriteOperation(client, hoodieRecords, commitTime, operation)
> {code}
> For example, I start the spark job at 201901010000, but *isEmpty()* ran for 2 hours, then the commit time in the .hoodie folder will be 201901010*2*00. If I use the commit time to ingest data starting from 201901010200(from HDFS, not using deltastreamer), then I will miss 2 hours of data.
> Is this set up intended? Can we move the commit time before isEmpty()?
