STORM-1504: Add Serializer and instruction for AvroGenericRecordBolt
This was new for me, so some questions I have:
- Would be better to automatically register this serializer instead of
providing developer instructions?
- What's the best practice for exception handling in a serializer? Throwing
a RunTimeException seemed like the best option.
Provided this PR is accepted, I would also vote for backporting this to
1.0.0 since the AvroGenericRecordBolt is unusable without it in a multi-worker
topology.
