dawidwys opened a new pull request #14324:
URL: https://github.com/apache/flink/pull/14324
## What is the purpose of the change
Using the batch state backend requires that the inputs are sorted by a key.
Right now when sorting, we sort either all of the inputs or none. It is because
we expect that the same key is consumed from all inputs at the same time.
We throw an exception if such a combination is used.
## Verifying this change
Added tests:
*
`org.apache.flink.streaming.api.graph.StreamGraphGeneratorBatchExecutionTest#testMixingKeyedAndNonKeyedInputInBatchMode`
*
