Hi all.! As discussed in the community meeting held on last week of Feb 2021, we already have plan to make Secondary Index as a Coarse Grain Datamap in the future. And It would be more appropriate for this requirement to implement Secondary Index as the CG Datamap. Presto query can leverage secondary index in the pruning through the datamap interface. Spark queries can still continue to make use of secondary indexes with existing approach of query plan modification.
Have added the detailed design in the below doc. https://docs.google.com/document/d/1VZlRYqydjzBXmZcFLQ4Ty-lK8RQlYVDoEfIId7vOaxk/edit?usp=sharing Please review it and let me know your suggestions/inputs.
