pratyakshsharma commented on issue #1362: HUDI-644 Enable user to get checkpoint from previous commits in DeltaStreamer URL: https://github.com/apache/incubator-hudi/pull/1362#issuecomment-593306470 @garyli1019 If I understand it correctly, you are talking of a use case where you are using HoodieDeltaStreamer along with using spark data source as a backup. Why do you want to have two different pipelines writing to the same destination path? If you really want to have a backup to prevent any data loss, you can write to a separate path using spark data source and continue using DeltaStreamer to write to Hudi dataset. In case of any issues, you can always use CHECKPOINT_RESET_KEY to ingest the data from your back up path into your Hudi dataset path. We have support for kafka as well as DFS source for this purpose. Also what is the source for your homebrew spark? If it is also consuming from kafka, then I do not see any case where using DeltaStreamer can result in data loss. Can you please explain why do you want to use two pipelines for writing to the same destination path?
