Hi Folks:
I am using 'kafka' connector and joining with data from jdbc source (using
connector). I am using Flink v 1.14.3. If I do a left outer join between
kafka source and jdbc source, and try to save it to another kafka sink using
connectors api, I get the following exception:

How can you achieve that in Flink? maybe I should use coGroup?
Yes, currently you have to implement
Do you have an already working example of it? :)

I think this may be a great example to add as a utility function.
Or actually add as an function to the DataSet, internally realized as a
special case of coGroup.
We do not have a ready example of that, but it should be straightforward to
realize. Similar as for the join, coGroup on the join

Hi Flavio,

As Stephan pointed out, this can be very easily modified to construct a
Right Outer Join (just exchange leftElements and rightElements in the two
loops).
