custom_datasource example panicked during RepartitionExec planning #15493
Description
Describe the bug
I have a PR that didn't change the repartition code, but caused one assertion failure inside RepartitionExec's execute() method, during custom_datasource.rs example's execution.
The failed CI job run: https://github.com/apache/datafusion/actions/runs/14152369014/job/39647355093
After re-running, the CI it passed, this might be some heisenbug which occurs rarely?
