@pzhdfy Thanks for the reply. If `paimon-cpp` currently looks slower than the Java implementation, I wonder whether it could be related to configuration. A few points that may be worth double-checking: - **Some read-path optimizations in `paimon-cpp` are disabled by default**, so it might be worth testing again with `EnablePrefetch`, `EnableMultiThreadRowToBatch`, and `SetRowToBatchThreadNumber(3)` enabled. - **In our internal tests, we observed roughly a 2–4x E2E performance improvement** over the Java-based path after enabling the relevant optimizations. - **For pushdown performance, `paimon-cpp` master has already been optimized to support page-level pushdown**, which reduces latency by an order of magnitude compared with the previous implementation (for example, https://github.com/alibaba/paimon-cpp/pull/316 334 375 424) Looking forward to seeing more testing and results. -- This is an automated message from the Apache Git Service.
