Ehcache: Once configured what cache replication algorithm is followed?

Question

I am looking for replicating cache. I had gone through the manuals of Ehcache. It only guides about configuration. I need to understand replication from performance prospective.

• Which node will go first in replication?
• What if two peers start caching at the same time?
• In a write extensive application, how ehcache manages the synchronization?
• Which strategy is better JMS, RMI or JGroup.

Answer 1

There is no synchronization in replicated setups. Replication is inherently racy (to your point #2 & #3). You shouldn't make any assumption on what node the replication will go first, but probably which it firsts get to. That may help answering question #4.

If you want some guarantees around consistency, you should probably cluster your Cache with Terracotta instead.
