voldemort.serialization.protobuf
Class ProtoBufSerializer<T extends com.google.protobuf.Message>

java.lang.Object
  voldemort.serialization.protobuf.ProtoBufSerializer<T>

All Implemented Interfaces:

Serializer<T>

public class ProtoBufSerializer<T extends com.google.protobuf.Message>
extends java.lang.Object
implements Serializer<T>

A serializer that relies on Protocol Buffers for serialization and deserialization. Only Java clients are supported currently, but there are plans to support clients in other languages. An example configuration of a value-serializer follows.

 <value-serializer>
   <type>protobuf</type>
   <schema-info>java=com.linkedin.foobar.FooMessage</schema-info>
 </value-serializer>
 

Once support for clients in other languages is available, a comma-separated list will be accepted for the schema-info element (one for each language).
