Samarth Jain updated PHOENIX-3444:
----------------------------------
Comment: was deleted
(was: The idea of having new/old methods was really to help us just remove code
when we rollout our next major release. The alternative was to have code with
branches on isNewClient/isOldClient which would have made it a bit ugly, IMHO.
I also looked at seeing whether I can just getaway with not storing the
coveredColumnsMap for non-encoded tables. It turns out, the indexmaintainer
already tracks this information in two datastructures - coveredColumns set and
indexedQualifiers list. The coveredColumnsMap is now just a single place where
we track this. I can make coveredColumns set deprecated just like I did for
indexedQualifiersList and dataTableLocalIndexFamilyMap since the information is
already available in the newly added coveredColumnsMap. )
> Make changes to IndexMaintainer backward compatible
