@pratyakshsharma Because our department uses nifi to extract data and then
push it to Kafka, and the nifi processor uses ByteArraySerializer, I want to
support ByteArrayDeserializer in Hudi.As for the benefits, I'm not very clear
now,But I don't think it's very convenient to register a
'schema.registry.url'.And I found a problem in the local virtual machine
verification today. I passed the verification in the company's test environment
before. I don't know if there is a problem with my environment settings. I'll
verify and solve it later

> When the 'value.serializer' of Kafka Avro Producer is
> 'org.apache.kafka.common.serialization.ByteArraySerializer',Use the following
> configuration
> {code:java}
> --source-class org.apache.hudi.utilities.sources.AvroKafkaSource \
> --schemaprovider-class
> org.apache.hudi.utilities.schema.JdbcbasedSchemaProvider \
> --hoodie-conf
> "hoodie.deltastreamer.source.kafka.value.deserializer.class=org.apache.kafka.common.serialization.ByteArrayDeserializer"
> {code}
> For now,It will throw an exception::
> {code:java}
> java.lang.ClassCastException: [B cannot be cast to
> org.apache.avro.generic.GenericRecord{code}
> After support ByteArrayDeserializer,Use the configuration above，It works
> properly.And there is no need to provide 'schema.registry.url',For example,
> we can use the JdbcbasedSchemaProvider to get the sourceSchema
