Lars Hofhansl updated PHOENIX-4882:
-----------------------------------
Description:
See TupleProjectionCompiler.ColumnRefVisitor.
Each non-projected column causes a server roundtrip in LocalIndexDataColumnRef.
For wide tables that can be hundreds of time.
I generally find that the same table is resolved over and over again for other
reasons as well (I counted 15-20 times during query compilation.)

> The client re-resolves the table for every projected non-indexed column when
