## Which issue does this PR close? Related to #21637. ## Rationale for this change This adds a ClickBench extended query that can be used to measure filter-only string prefix matching on Parquet data. It is intended to help evaluate optimizations that skip RowFilter evaluation when row group statistics prove the predicate fully matches a row group. ## What changes are included in this PR? - Adds `benchmarks/queries/clickbench/extended/q13.sql` - Documents the new extended query in the ClickBench README The query filters on `URL LIKE 'http%'` but only projects and aggregates `CounterID`, so the URL column is only needed for filter evaluation. ## Are these changes tested? Ran: - `cargo fmt --all -- --check` - `git diff --check` I did not run the ClickBench benchmark locally because the benchmark dataset is not available in this worktree. I did not run full clippy because this PR only adds SQL/README benchmark files. ## Are there any user-facing changes? No. This only adds a benchmark query. -- This is an automated message from the Apache Git Service.
