DataNucleus and Cache Coordination

Question

Does DataNucleus support Cache Coordination? If yes, how can I enable and use it?

I'm not actively using DataNucleus yet, but I want to consider it, if it supports Cache Coordination.

Background: Cache coordination is used by multiple cache instances to inform each other about changed entities (e. g. via JMS or RMI). Its purpose is to reduce the number of failed or repeated transactions (similar to what e. g. EclipseLink provides?)

Answer 1

I might be wrong but from what I can read in the documentation about JPA Caching or JDO Caching, the DataNucleus built-in implementations for Level 2 caching (the internal weak and soft reference based L2 caches) do not support distributed caching so no coordination when using them. But you can use one of the other pluggable implementations that might offer this option (Oracle Coherence does for example).
