PyRSA opened a new pull request, #8578: URL: https://github.com/apache/paimon/pull/8578
### Purpose Introduce `nested_partial_update` aggregator function This change adds support for the `nested_partial_update` aggregation function in the Python reader, aligning its behavior with the Java implementation. It supports nested-key based partial updates, where only non-null fields overwrite existing values, while configurable nested-key null handling ensures consistent behavior with the Java implementation. ### Dependency This PR depends on #8577 and reuses several shared utility methods introduced there. Please review and merge #8577 first. ### Tests - `python -m pytest pypaimon/tests/test_field_aggregators.py::FieldNestedPartialUpdateAggTest -q` - `git diff --check` -- This is an automated message from the Apache Git Service.
