SubhamSinghal opened a new pull request, #23524:
URL: https://github.com/apache/datafusion/pull/23524
## Which issue does this PR close?
- Follow-up to review feedback on #23217.
## Rationale for this change
The row-filter planner in `datafusion-datasource-parquet` walks the accessed
struct-field paths for every filter, resolves the Parquet leaves, and builds a
pruned Arrow schema. When multiple predicates share a common struct prefix, the
planner can consolidate that traversal work — this is the case the
`StructAccessTree` refactor in #23217 is intended to accelerate.
The existing bench suite does not cover this shape:
- `parquet_struct_query` — single-field struct predicates only
(`WHERE s['id'] = 5`).
- `parquet_struct_projection` — projection-only, no `WHERE` clause.
So multi-conjunct shared-prefix planning is currently uninstrumented, and
the effect of consolidating access-path traversals is invisible against the
existing suite.
## What changes are included in this PR?

No. Benchmark-only; no library or API surface is touched.
