Class AvroSerializationProvider

java.lang.Object

org.hibernate.search.indexes.serialization.avro.impl.AvroSerializationProvider

All Implemented Interfaces:

Service, Startable, SerializationProvider

public class AvroSerializationProvider
extends Object
implements SerializationProvider, Startable

Avro based implementation of SerializationProvider.

Parsing code inspired by http://www.infoq.com/articles/ApacheAvro from Boris Lublinsky

Before the actual serialized flux, two bytes are reserved:

• majorVersion
• minorVersion

A major version increase implies an incompatible protocol change. Messages of a majorVersion > current version should be refused. A minor version increase implies a compatible protocol change. Messages of a minorVersion > current version are parsed, but new operation will be ignored or rejected. If message's major version is < current version, then the implementation is strongly encouraged to parse and process them. It is mandatory if only message's code minor version is < current version.
