### Is your feature request related to a problem or challenge? Currently, the benchmarks folder in DataFusion does not include dedicated benchmarks for TopK queries (i.e., queries formatted as `SELECT ... ORDER BY a LIMIT n`). With ongoing work to optimize these types of queries, having dedicated benchmarks would be valuable for measuring progress. ### Describe the solution you'd like There are already sorting benchmarks based on the TPCH dataset. Since a TopK query is essentially a sort operation with an additional limit, we can extend the existing `sort_tpch` benchmarks by introducing an optional `LIMIT n` clause. This modification would effectively convert them into proper TopK benchmarks. ### Describe alternatives you've considered _No response_ ### Additional context Relevant recent issues: - https://github.com/apache/datafusion/issues/15037 - https://github.com/apache/datafusion/issues/15529 - https://github.com/apache/datafusion/issues/15538 -- This is an automated message from the Apache Git Service.
