> Calcite planner: Add direct no-fallback regression harness
> ----------------------------------------------------------
>
> Key: IMPALA-15237
> URL: https://issues.apache.org/jira/browse/IMPALA-15237
> Project: IMPALA
> Issue Type: Sub-task
> Components: Frontend
> Reporter: Aleksandr Efimov
> Assignee: Aleksandr Efimov
> Priority: Major
> Fix For: Impala 5.0.0
>
>
> Calcite planner regressions can be hidden when Frontend retries a query with
> the Original planner. Add a test-only direct planning harness that exercises
> Calcite parsing, analysis, logical optimization, and conversion without going
> through Frontend fallback.
> The harness should expose the optimized logical RelNode immediately before
> Impala conversion together with client-visible output labels and exact
> Calcite output types. Add a compact synthetic corpus covering supported
> operators and an explicitly unsupported complex-type case.
