zhuxiangyi opened a new pull request, #967:
URL: https://github.com/apache/paimon-rust/pull/967
### Purpose
Linked issue: #964 (part 3 of 4)
> Stacked on #965. Only the last commit, "feat(python): expose
Table.expire_snapshots", is new
> here.
Expose snapshot expiration from #965 to Python.
### Brief change log
- `Table.expire_snapshots(retain_max=None, retain_min=None,
older_than_ms=None, max_deletes=None)
-> int` in the Python binding. Unset arguments fall back to the table
options, as in `CALL
sys.expire_snapshots`. The call releases the GIL while it runs and returns
the number of expired
snapshots.
- Type stub and docstring in `datafusion.pyi`.
### Tests
- `tests/test_table.py::test_expire_snapshots` covers:
- the defaults keep recent snapshots;
- `retain_max` / `retain_min`;
- `older_than_ms` with `max_deletes`;
- the latest data and a tagged snapshot stay readable;
- invalid retention raises `ValueError`.
- `make install && make test` for `tests/test_table.py` passes (24 tests),
and so does clippy with
`-D warnings`.
### API and Format
New Python method `Table.expire_snapshots`. No format change.
### Documentation
Docstring in the type stub.
