Problem Currently, the delta input source only supports reading from the latest snapshot of the given Delta Lake table. This is a known documented limitation. Description Add support for reading Delta snapshot. By default, the Druid-Delta connector reads the latest snapshot of the Delta table in order to preserve compatibility. Users can specify a snapshotVersion to ingest change data events from Delta tables into Druid. In the future, we can also add support for time-based snapshot reads. The Delta API to read time-based snapshots is not clear currently.
