Description

Schema coders for Avro enums don't work. Avro enum should become Schema STRING before we have a logical type for enums in java-sdks-core. Using STRING for serialization is very sub-optimal, but would provide good integration with the rest of the features out of the box.

As a follow-up, we need to figure out if we can have a dedicated logical type for enums.
