XiaoHongbo-Hope opened a new pull request, #1238: URL: https://github.com/apache/paimon-rust/pull/1238
## Purpose Add an Arrow batch temporal matching kernel for PyPaimon alignment. It returns matching positions for grouped as-of joins, interpolation brackets and windows, avoiding one Python binary search per anchor row. The kernel accepts sorted, non-null int64 keys and validated group bounds, releases the GIL while matching, and uses i128 arithmetic for timestamp limits. Duplicate selection, nearest ties, exact-match exclusion, tolerance and window closure follow PyPaimon's existing semantics. It performs no table reads or writes. ## Validation - Rust kernel boundary tests pass. - Python binding differential tests and the PyPaimon integration suite are included; full extension validation is in progress. -- This is an automated message from the Apache Git Service.
