pnowojski opened a new pull request #6776: [FLINK-9715][table] Support temporal join with event time
URL: https://github.com/apache/flink/pull/6776
 
 
   This PR adds support for temporal joins with event time. I haven't yet written the documentation for this feature, since it will have to base on the documentation that is still undergoing the review: https://github.com/apache/flink/pull/6741
   
   ## Verifying this change
   
   Refactoring is covered by existing tests, while for the new features there are added new unit tests and IT test cases.

     - Dependencies (does it add or upgrade a dependency): (yes / **no**)
     - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**)
     - The serializers: (yes / **no** / don't know)
     - The runtime per-record code paths (performance sensitive): (**yes** / no / don't know)
