Could someone with permissions start off the workflow for https://github.com/apache/parquet-java/pull/3481
Neelesh Salian is working on variant performance and features across the stack and this PR extends the work I've done (and uses the flame graphs from my benchmarks @ https://github.com/steveloughran/benchmarking-variants/tree/main/results/parquet-performance ) to identify more tuning. thanks
