The AvroGenericRecordBolt expects to receive tuples containing an Avro
GenericRecord that conforms to the provided
schema.
+To use this bolt you **must** register the appropriate Kryo serializers
with your topology configuration. A convenience
+method is provided for this:
+
+```AvroGenericRecordBolt.addAvroKryoSerializations(conf);```
+
+By default Storm will use the ```GenericAvroSerializer``` to handle
serialization. This will work, but there are much
+faster options available if you can pre-define the schemas you will be
using or utilize an external schema registry. An
+implementation using the Confluent Schema Registry is provided, but others
can be implemented and provided to Storm.
+Please see the javadoc for classes in org.apache.storm.hdfs.avro for
information about using the built-in options or
+creating your own.
