-------------------------------------
Resolution: Not A Bug
> Projection pushdown does not occur with Calcite upgrade
> -------------------------------------------------------
>
> Key: DRILL-6226
> URL: https://issues.apache.org/jira/browse/DRILL-6226
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.13.0
> Reporter: Gautam Kumar Parai
> Priority: Major
> Fix For: 1.13.0
>
>
> I am seeing plan issues where projection pushdown does not occur due to
> costing. The root cause is in DrillScanRel we are relying on utility
> functions to determine STAR columns which fails with the Calcite upgrade -
> because GroupScan is using GroupScan.ALL_COLUMNS which is different from
> STAR_COLUMN/DYNAMIC_STAR.
> While looking at references of SchemaPath.STAR_COLUMN, we found comparisons
> involving hardcoded '*'. These might also need to change to accommodate for
> DYNAMIC STAR.
> [~arina] [~amansinha100] please let me know your thoughts on this issue.
