Users can ingest data stored in a Delta Lake table into Apache Druid via a new input source `delta`. This is available via the Delta Lake extension, add the `druid-deltalake-extensions` to the list of loaded extensions. The Delta input source reads the configured Delta Lake table and extracts all the underlying delta files in the table's latest snapshot. Delta Lake files are versioned Parquet format. This is joint work with @abhishekagarwal87, @LakshSingla and @AmatyaAvadhanula.
