---------------------------------------
Hi [~pvillard],
I didn't realize that it's avro limitation. I guess we have to build some
custom processor to handle the issue. We need avro so the JSON writer is not a
option for us.
Thanks for clarifying the root cause.

> Hi
> We have some incoming data that where the type is map. Problem is that key is
> int and not string which cause the map to have invalid data.
> Can Nifi add support for other data types for map keys as well?
> I have attached dummy example flow for example.
> If there is any good workaround that would be good start.
