it completely depends on your model, your infrastructure, your services (CS, Memcache, Hazelcast, whatsoever), your demands on availability, consistency, latency and so on. There is no wrong or false. Maybe you get 50% better performance with a Memcache in front of CS, or you just use ScyllaDB and

No, I haven’t “thought why people don’t use Cassandra as a cache”, that’s why I’m asking this here. I’m asking the community for their POV when it might make sense to front Cassandra with Hazelcast. This is even mentioned as a use case in the Hazelcast documentation (“As a front layer for a

Rationale for using Hazelcast in front of Cassandra?

2016-10-06 Thread KARR, DAVID
I've seen use cases that briefly describe using Hazelcast as a "front-end" for Cassandra, perhaps as a cache. This seems counterintuitive to me. Can someone describe to me when this kind of architecture might make sense?

I don't know much about Zookeeper, but as far as I read, it is out of JVM process. Hazelcast is just a framework and you can programmatically start and shutdown the cluster, it's just an xml to configure it. Hazelcast also provides good caching features to integrate with Hibernate, d
