Vihang Karajgaonkar commented on HIVE-20306:
--------------------------------------------
Latest patch adds support for JDO code path as well. As long as the projected
fields contain single-valued fields, patch uses Query.{{setResult}} to fetch
only partially filled partitions. If there are multi-valued fields in the
projected list, JDO code path will return the fully filed partitions since JDO
doesn't support multi-valued fields in \{{setResult}}
> Implement projection spec for fetching only requested fields from partitions
