Distributed Caching [closed]

Answer 1

I'm late to the party but have you tried TayzGrid, an open source java distributed cache. Also known as in-memory data grid or key value store.

It answers all your basic needs

- Distributed
- Auto-Discovery
- Redundancy
- Non-Centralized

It also manages advanced failover scenarios like split brain and sudden restarts. All nodes are intelligent therefore completely distributed.

You also can also make a choice of which topology you want to use (Partition or replicated). If you want to use more advanced topologies(Partition of replica) then you can maybe buy a license.

Answer 2

Normally single point of failure occurs when all the operation are done on a single node and if that node goes down, the whole operation can go down. the solution of this problem is to use topology like Replica or partition replica. if once node goes down, the whole operation will shift to an other node without any kind of data lose.

as far as the features which you are looking can be found in a single product, NCache,as Umer has also mentioned.
