How do I configure infinispan in capedwarf for persistent store behavior?

[jofrantoba]

Hi, I'm Jonathan.

I'm using capedwarf. Capedwarf(Wildfly) is a project that provides platform-like features as a Google App Engine service. Capedwarf uses Infinispan(Infinispan 6.x) to store the data. Everything works fine in an on / off environment of capedwarf, but when there are unexpected shutdowns of capedwarf or the server itself due to power outages, I have data loss in infinispan. I need infinispan sure to always write write to disk and prevent the loss of data. Please help me with the correct settings.

I leave here the configuration in capedwarf for infinispan that is currently in use:

I don't know specifics about Capedwarf, but the typical thing to is to first, figure out which caches are relevant for the state that you want to keep across restarts, then add persistent stores for them. If using file based persistence, a restart might remove those too, so they'd need to point to a filesystem that survives restarts, or use a DB of some sort.
