For the configuration change, there are certain design decisions that need to be made: > a) We need to introduce two configuration params staggered_get_flag and staggered_get_timeout. Where exactly are these params specified in the cache configuration file. At the global or the cache level and under what element. Are they be implemented as attributes of clustering element, separate element as a child of clustering or cache. What about something like: <cluseter> <remoteReads policy="ALL|STAGGER|MAIN_OWNER" staggerTimeout="50"/>

</cluster> What others think? > b) once we read the properties second big question is how to pass them on to the dispatcher in question i.e CommandAwareRpcDispatacher.

I'm not sure the CARD needs to be aware of the staggering. I'd think it is the responsibility of the caller (DistributionInterceptor) to orchestrate staggering.. > > Also, would the changes in configuration would require making a change in XSD schema file? > > Thanks! > Hammad > > > ` Cheers, -- Mircea Markus Infinispan lead (www.infinispan.org)
