Resolution: Won't Fix
We should do IMPALA-15629 instead.
> Push down predicates on sorting columns to Iceberg
> --------------------------------------------------

> Key: IMPALA-12173
> URL: https://issues.apache.org/jira/browse/IMPALA-12173
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Reporter: Zoltán Borók-Nagy
> Assignee: Dániel Gábor Vankó
> Priority: Major
> Labels: impala-iceberg, performance, ramp-up
>
> Currently we only push down predicates to Iceberg if any of them refers to a
> partitioning column. We do this because invoking Iceberg's planFiles() API is
> very expensive, so we only want to do that if we can expect greater benefits.
> We could also push down predicates if any of them refers to a sorting column.
