jakob-ed opened a new pull request #15152: URL: https://github.com/apache/flink/pull/15152
## What is the purpose of the change Adds a source connector implementation following [FLIP-27](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=95653748#FLIP27:RefactorSourceInterface-PublicInterface) to consume messages from Google Cloud Pub/Sub. ## Brief change log - Add basic Pub/Sub source using new interface - Add checkpointing and do some refactorings - Allow multiple records inside single Pub/Sub message for deserialization - Add Javadocs, README and clean up ## Verifying this change A new end-to-end test `EmulatedPubSubNewSourceTest.java` was added to verify these changes. However, currently the test never finishes and instead keeps waiting for new input records forever. The end-to-end test for the old source (`EmulatedPubSubSourceTest.java`) uses a stop marker mechanism to finish the test. I tried out different things to apply it to the new source end-to-end test but without success.
