chore: refactor `MaterializingSortMergeJoinStream` into generators and simplify code to be textbook like as possible by rluvaton · Pull Request #23976 · apache/datafusion

rluvaton · 2026-07-29T15:05:05Z

Which issue does this PR close?

Part of:

[Status Update] Simplifing Streams to be more textbook-like and have less state while keeping the same perf #23974

Rationale for this change

Simplify the code and make code similar to textbook so it is easier to read

What changes are included in this PR?

Changed to async generators + simplified to be similar to textbook

Most of the code was written by Claude Fable 5 since it was just too large to comprehend in head

Are these changes tested?

existing tests + a little more tests to verify we are not counting the childs in the join time

Are there any user-facing changes?

The join_time now includes the time to read from the async spill stream between pending which is arguable more correct since this time is part of the operator, although long waits between pending calls will be counted in the op join_time while the alternative is not counting the read from file and decoding...

Tracks with what I saw in #23761. Tests are green, added tests look good, and performance looks the same. Thanks @rluvaton!

- match ready!(self.spill_stream.as_mut().unwrap().poll_next_unpin(cx)) {
- Some(Ok(batch)) => {
+ match spill_stream.next().await.transpose()? {


restore_spilled_batches awaits the spill stream here without stop_join_time()/start_join_time() around it, per the stop_join_time doc comment: "The join's own spill write and read-back are NOT excluded — that time is join work." That's a real change from the old poll_next, which returned out via ready!(self.poll_spilled_batches(cx, ...)) on a genuine Poll::Pending, stopping _timer for that wait.
This is the same join_time semantics change #23761 required calling out before merge (that PR's description was updated to note the metric now includes spill read-back time). This PR's description currently says "Are there any user-facing changes? nope" — worth adding the same note here, since join_time is visible in EXPLAIN ANALYZE.

…d simplify code to be textbook like as possible (apache#23976) ## Which issue does this PR close? Part of: - apache#23974 ## Rationale for this change Simplify the code and make code similar to textbook so it is easier to read ## What changes are included in this PR? Changed to async generators + simplified to be similar to textbook Most of the code was written by Claude Fable 5 since it was just too large to comprehend in head ## Are these changes tested? existing tests + a little more tests to verify we are not counting the childs in the join time ## Are there any user-facing changes? The join_time now includes the time to read from the async spill stream between pending which is arguable more correct since this time is part of the operator, although long waits between pending calls will be counted in the op `join_time` while the alternative is not counting the read from file and decoding...
