A somewhat related question concerning the `ExecutionSlotSharingGroup` is the following: How will the `ExecutionSlotSharingGroup` be calculated if we have the following JobGraph: ``` v1 --> v2 v3 --> v4 ``` here `v1, v2, v3, v4` are `JobVertices` and `-->` is a blocking data exchange. Given this specification we can say that neither `v1` and `v2` can share slots because of the blocking data exchange. The same applies for `v3` and `v4`. However, `v3` or `v4` could share the slot with `v1`. How is this solved? Will the effective execution slot sharing group for `v1` contain `v3` and `v4`? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
