Gokcen Iskender updated PHOENIX-6120:
-------------------------------------
Description:
This Jira is a followup Jira of PHOENIX-5923 where data and index might have
different storage and encoding formats. IndexMaintainer and protobuf needs to
change to handle this. Right now, index maintainer assumes both index and data
tables have the same format. The protobuf needs to be changed so that
IndexMaintainer knows about the data table storage and encoding formats
Repro:
# Create a table with ONE_CELL_PER_COLUMN storage format
# Create an index that has covered columns and the IMMUTABLE_STORAGE_SCHEME is
SINGLE_CELL_ARRAY_WITH_OFFSETS
# Upsert rows to data table
# Query the covered column using index --> Null value is returned even though
there is a value.
IndexMaintainer has a 4 year old code that doesn't return a value for covered
columns,

Summary: Change IndexMaintainer for SINGLE_CELL_ARRAY_WITH_OFFSETS
indexes. Currently it assumes data and index table having the same storage and
encoding format. (was: Covered columns of indexes that have
SINGLE_CELL_ARRAY_WITH_OFFSETS storage doesn't handle those columns)
