Re: [infinispan-dev] Ditching ASYNC modes for REPL/DIST/INV/CacheStores?

Generally I like the systems designed with SYNC_DIST + async shared cachestore. It's probably the best setup we can offer: - you need a shared cachestore for persistence consistency - using SYNC distribution to other replicas provides a fairly decent resilience - if your cachestore needs to be updated in sync, your write performance will be limited by the cachestore performance: this prevents you to use Infinispan to buffer, absorbing write spikes, and reducing write latency

But I agree we should investigate on removing duplicate "asynchronizations" where they are not needed, there might be some opportunities to remove thread switching and blocking.

So, this would mean that when you call put(), it's always sync. This would reduce the complexity and configuration of our code base, without affecting our functionality, and it would make things more logical IMO. >>> >>> WDYT? >>> >>> Cheers, >>> -- >>> Galder Zamarreño >>> galder(a)redhat.com >>> twitter.com/galderz >>> >>> Project Lead, Escalante >>> http://escalante.io >>> >>> Engineer, Infinispan >>> http://infinispan.org >>> >>> >>> _______________________________________________ >>> infinispan-dev mailing list >>> infinispan-dev(a)lists.jboss.org >>> https://lists.jboss.org/mailman/listinfo/infinispan-dev >> _______________________________________________ >> infinispan-dev mailing list >> infinispan-dev(a)lists.jboss.org >> https://lists.jboss.org/mailman/listinfo/infinispan-dev >> > > _______________________________________________ > infinispan-dev mailing list > infinispan-dev(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/infinispan-dev _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
