@adfel70 thanks for the contribution! I'm a bit concerned about the
ramifications of this change as-is, though. If I'm understanding the code
change, it appears to be removing all caching from the controller service. I
don't think that's what we want to do, as network problems or having the
Confluent Schema Registry go down would cause the dataflow to stop. I think if
we want to avoid the caching mechanism, then we would need to expose a property
to allow the user to choose whether or not they want to do so - or how long
they want to cache the schema.
