[infinispan-dev] Retrieving value before write

Hi, Pedro suggested moving the following idea to separate thread (from the 'Improve WriteCommand processing code...'). Re: I've been wondering for a while why the fetch part is a separate message in the write flow. Is the return value of much use when it does not return really the replaced value but only some of the previous values? And this way you double* the latency. I think that returning the value from primary owner as the response for write would make more sense. Naturally, for optimistic txs you can only do the get, and for pessimistic ones you'd have to return the value together with the locking, but still, the operations would make more sense. *: OK, it's not doubling as with the write the primary owner replicates the write to backups, but it's doubling the amount of communication originating from the requestor node. WDYT? Radim
