public class GrpcMetaDataConverter extends Object
To optimize communication and minimize the loss of data structure, the MetaDataValue entries used in gRPC
distinguish between numerical values (double or long), Strings, booleans and arbitrary objects. The latter group is
converted to and from a byte[]
using the configured Serializer.
