[infinispan-dev] Hot Rod clients & payload size estimates

Hi all, I just noticed that the payload size estimates are ignored by the Hot Rod client when using the ProtoStreamMarshaller. That sounds good, as the estimating strategies are typically based on dumb statistics, while in case we're using protobuf-encoded data we have a schema which implies the ProtoStreamMarshaller could know better.. however this marshaller doesn't seem to try optimise the buffer size at all. Some types in protobuf will still need variable lenght encoding for obvious reasons (i.e. encode a String type), but some message types could have a pre-computed constant size. Even for those messages which include some variable length fields we could define at least: - a minimum size - try guess a good a reasonable default size depending on the type and number of fields - a per- message type sampler? With the OGM Grid Dialect for Hot Rod I'm sending several different kinds of objects over the wire, which implies wildfly different buffer sizes. Would be nice to be able to control this better? Thanks, Sanne
