Maryann Xue updated PHOENIX-2678:
---------------------------------
Labels: calcite (was: )
> Replace calcite default RelOptCostFactory
> -----------------------------------------
>
> Key: PHOENIX-2678
> URL: https://issues.apache.org/jira/browse/PHOENIX-2678
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Maryann Xue
> Assignee: Maryann Xue
> Labels: calcite
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> Right now we apply a PHOENIX_FACTOR on the cost calculated from PhoenixRel to
> prioritize PhoenixRel over EnumerableRel, but this has greatly limited the
> way we implement costing for PhoenixRel.
>
> Having a different RelOptCost/RelOptCostFactory can be a solution. We can
> make PhoenixRel always generate a cost with getRows() always less than that
> of EnumerableRel while having our own RelOptCost implementation to compare
> the rest two fields.
