Looks good. Is there any way to add a unit test for this?

Thanks, if the avro.schema attribute is coming through on flowfiles coming out of the runner, then that sounds good to me. The simplest test would be to see that the attributes are now returned from the method I added, but I noticed that at run time it didn't come through until I added a schema cache service. Entirely possible I didn't understand how the schemas worked, and that setting it to use schema name(?) should work.
