Infinispan singleFileStore cache restartability

Question

I am using infinispan 6.0.1 release, I have configured it to use SingleFileStore as loader

Configuration is as below

<namedCache name="MyCache">
 <persistence passivation="true">
    <singleFile fetchPersistentState="true"
                 ignoreModifications="false"
                 purgeOnStartup="false" maxEntries="5000">
     </singleFile>
  </persistence>

My question is, will this cache survive JVM restarts? I mean lets say my cache is holding {n} entries and my jvm goes down. When JVM starts again will my cache initialized with {n} entries?

Thanks in advance!!

Answer 1

With passivation, the entry is EITHER in memory (activated) OR in cache store (passivated). Therefore, no, it won't.

Answer 2

With passivation enabled, my understanding is, that everything only present in memory will persisted during shutdown. However, I cannot find proof in the InfiniSpan documentation now.

Anyway, keep in mind that the SingeFileStore is not a robust implementation. The stored value will only survive, if you do a correct shutdown.
