BiteTheDDDDt opened a new pull request, #58068:
URL: https://github.com/apache/doris/pull/58068
### What problem does this PR solve?
This pull request updates the partitioning logic in the
`ExchangeSinkOperatorX` constructor to improve handling of destination
fragments. The changes simplify the condition for partition type selection and
adjust the partition type assigned when only one destination fragment is
present.
Partitioning logic improvements:
* Removed the special case for `BUCKET_SHFFULE_HASH_PARTITIONED` so that
only `UNPARTITIONED` partitions are excluded from further partitioning logic.
(`be/src/pipeline/exec/exchange_sink_operator.cpp`)
* Changed the assignment when there is only one destination fragment from
`UNPARTITIONED` to `RANDOM`, ensuring more appropriate partitioning behavior in
single-destination scenarios.
(`be/src/pipeline/exec/exchange_sink_operator.cpp`)
