[PR] [Python] Keep append distribution native end to end [paimon]
JingsongLi opened a new pull request, #10032:
URL: https://github.com/apache/paimon/pull/10032
## Summary
- forward ordinary append slice and shard distribution into native planning
- keep the native split opaque instead of rebuilding it as a Python SlicedSplit
- require the row-position planning methods whenever non-primary-key distribution is requested
- preserve exact LIMIT behavior for deletion-vector selections by leaving selected splits intact for the reader
- turn the distribution and incremental parity suites into true Native Plan + Native Read tests that fail on Python reader fallback
- add row-tracking and partition-pruned ordering coverage and update the Python README
Depends on apache/paimon-rust#893.
## Tests
- PYTHONPATH with the paimon-rust #893 binding pytest -q --tb=short paimon-python/pypaimon/tests/native_plan_*test.py (323 passed, 128 subtests passed)
- focused native plan and distribution tests (63 passed, 101 subtests passed)
- native_plan_distribution_test.py (16 passed, 48 subtests passed)
- native_plan_incremental_test.py (49 passed)
- git diff --check
