QuakeWang opened a new pull request, #10016: URL: https://github.com/apache/paimon/pull/10016
### Purpose Window `first` and `last` aggregates converted the entire window to Python objects before selecting one non-null value. Scan Arrow chunks from the requested endpoint and convert only the selected value, preserving null and value semantics. ### Tests - Temporal suite: 76 passed, including chunk, null, nested-value, dictionary, and memory regressions. - The memory regression fails on the previous implementation. - Local Python allocation peak for 8,192 binary values of 1 KiB each: 8.38 MiB to about 1.6 KiB. - Flake8, license headers, Python 3.6 syntax, and git diff --check passed. -- This is an automated message from the Apache Git Service.
