It rather boils down to the question whether it makes sense to do a green field design for a hypothetical standalone C/S marshalling protocol, or whether we just agree that we have to live ...

If a Predicate instance can be optimized to SODA on the client, the optimized SODA query will be passed on to server. Otherwise the Predicate will be wrapped inside a SODA Evaluation that will be passed to server. There currently is no notion of native ...

Hi, it's nice to see the C/S discussion getting going! Here is a completely different angle for tuning performance: What if we would store the byte slots of all YapObjects (References) that we hold in memory? That way we could do a compare on updating and store only the ones that changed. The mechanism could be optimized on a more fine-grained ...

The questions is: Is the binary data sequential, like a byte stream, or inconsecutive like slot1, slot2, slot3 ... ? The ...
