Lars Hofhansl updated PHOENIX-6115:
-----------------------------------
Description:
Looking at the code I realized that we retrieve the prior row state even when
is not necessary.
Specifically it is not necessary when (a) the table is immutable and (b) the
indexes does not include any covered columns.
> Avoid scanning prior row state for uncovered local indexes on immutable
> tables.
