----------------------------------------
Hi [[email protected]]. Checkpointing is currently not supported when using
input selection as it could lead to deadlocks. We are hoping to support it at
some point of time, but there is currently no timeline for implementing it.
I've created a ticket for tracking this issue
https://issues.apache.org/jira/browse/FLINK-17122
> Add JobGraph validators for the uses of InputSelectable, BoundedOneInput and
> BoundedMultiInput
