-----------------------------------------
Summary: 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
Assignee: Arina Ielchiieva
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.
