perf: coalesce batches before sending to distributor channels in RepartitionExec by gabotechs · Pull Request #22010 · apache/datafusion

🙈 Don't look yet, still experimenting

Which issue does this PR close?

Closes #.

Rationale for this change

Today RepartitionExec emits one small batch per (input batch × non-empty output partition), then coalesces those small batches back into target-sized ones on the consumer side. That means the channel layer (memory accounting, gate, await suspensions) does work proportional to num_partitions per input batch, even though each small batch only carries batch_size / num_partitions rows. Moving the coalescing producer-side, before the gate, collapses the channel traffic and reduces sensitivity to high output fanout.

What changes are included in this PR?

A producer-side coalescer per output partition, shared across input tasks, that runs before the channel's gate.
The redundant consumer-side coalescer in PerPartitionStream is removed.
BatchPartitioner is unchanged — only the layer between the partitioner and the channel.

Are these changes tested?

Yes, by existing tests

Are there any user-facing changes?

No

…butor channel, instead of after.
