Summary: Refine PhoenixTableScan.computeSelfCost() when scanRanges
is available
Key: PHOENIX-2090
URL: https://issues.apache.org/jira/browse/PHOENIX-2090
Project: Phoenix
Issue Type: Sub-task
Reporter: Maryann Xue
We should compute a more accurate cost based on the "scanRanges" so that we can
better choose among these different indices.
For example, if we have more than one indices concerning different index keys,
for example IDX1 is indexed on column a, and IDX2 is indexed on column b, and
our query is like "select x, y, z where a between 'A1' and 'A2' and b between
'B3' and 'B4'.
