6.2.5. Indexing Protobuf Encoded Entities

Once the client has been configured to use Protobuf, indexing can be configured for caches on the server side.

To be able to index the entries, the server must extract relevant metadata from the same binary descriptor as the client, that is, the .protobin file. The descriptor is supplied to the server by remotely invoking the ProtobufMetadataManager MBean via JMX.

The ProtobufMetadataManager is a cluster-wide replicated repository of protobuf descriptors. For each running cache manager a separate ProtobufMetadataManager MBean instance exists. The ProtobufMetadataManager ObjectName uses the following pattern:

The following signature is used by the method that registers the Protobuf descriptor file:

void registerProtofile(byte[] descriptorFile)

void registerProtofile(byte[] descriptorFile)
