> Calcite Planner: Support queries against virtual columns
> --------------------------------------------------------

> Key: IMPALA-14337
> URL: https://issues.apache.org/jira/browse/IMPALA-14337
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Fang-Yu Rao
> Assignee: Fang-Yu Rao
> Priority: Major
>
> Currently the Calcite planner in Impala does not support queries against
> virtual columns. We should consider adding the support for this.
> For instance, we should support the following query like Impala's classic
> frontend does.
> {code}
> [localhost:21050] default> select INPUT__FILE__NAME, id from
> functional.alltypestiny;
> Query: select INPUT__FILE__NAME, id from functional.alltypestiny
> Query submitted at: 2025-08-21 11:45:30 (Coordinator: http://fangyu:25000)
> Query state can be monitored at:
> http://fangyu:25000/query_plan?query_id=b447a77bcf99aac2:e471990900000000
