@snleee we do not plan to support CDC directly through this interface. This issue is more about using Flink to build segments and upload them directly to the controller with the intention of giving the user more control over the ingestion process. Whilst a delta lake might support the operations you mention, we only currently support INSERT/append through our connector. In some sense, we are tackling this problem in increments - eventually we will have to consider the delta lake semantics and synchronise the state between Pinot and the Delta lake by one of the two methods you describe. However, this is out of scope for the issue here which is narrowed to Flink and Pinot. It is entirely possible that this could fall away if there was enough segment / input file lineage to make the sync a reality - which could even be done via a spark job which optimises the delta lake and applies mutation. For our use case having the building blocks in place allows us to replay the INSERT operations from the delta lake from a given checkpoint / version into Pinot should we need to rebuild a table from scratch. -- This is an automated message from the Apache Git Service.
