[hibernate-issues] [Hibernate-JIRA] Resolved: (HSEARCH-836) Evaluate the need to send the writing schema over with the message

Evaluate the need to send the writing schema over with the message ------------------------------------------------------------------ Key: HSEARCH-836 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-836 Project: Hibernate Search Issue Type: Bug Components: serialization Affects Versions: 4.0 Reporter: Emmanuel Bernard Avro knows to read a message serialized by a different writer assuming certain conditions described in their spec http://avro.apache.org/docs/1.5.1/spec.html But both reader and writer schema should be provided up deserialization GenericDatumReader(Schema writer, Schema reader, GenericData data) Should we embed the schema with each message? It looks like a significant payload. If we don't, we can use the major.minor version numbers that are before the avro stream. But that will only work if the receiver is more recent that the writer. In all case, we need a prototype to test backward compatibility.
