aljoscha opened a new pull request #13828:
URL: https://github.com/apache/flink/pull/13828
## What is the purpose of the change
Currently, both sources and watermark/timestamp operators can emit
watermarks that we don't really need. We only need a final watermark in BATCH
execution mode.
**Note to reviewers: I'm not sure whether to add a new RuntimeMode enum or
use the existing RuntimeExecutionMode for this.**
## Brief change log
* turn SourceTransformation into a logical transformation and only create
the operator in the Translator
* make source aware of BATCH/STREAMING mode
## Verifying this change
* new tests that verify we don't emit watermarks in BATCH mode
