[hibernate-issues] [Hibernate-JIRA] Commented: (OGM-4) Write a decent default Infinispan configuration file

[Sanne Grinovero (JIRA)]

Sanne Grinovero commented on OGM-4:
-----------------------------------

The way the Infinispan defines the default configuration is the most general-purpose possible. When not found so, we can suggest a change in default configuration.
So we should argue if "general-purpose" in the universe of Infinispan applications is different than "general-purpose" in the context of OGM applications. In which ways?

- a Transaction Manager would be highly recommended, but you inject that already.
- batching? it's disabled by default, but The Lucene Directory requires batching as it uses it. OGM could likely benefit as well from it, but depending if you make use of it.
- shutdown? you close the CacheManager at SF.close() right? alternatively a JVM shutdown hook can be registered.
- fetchInMemoryState likely needs to be set to true, unless a shared persistent store is enabled.
- lazyDeserialization is false, looks good to me.
- L1 is disabled, likely the best option as invalidating remote L1 values is not complete so it might bring some complexity
- isolationLevel I guess READ_COMMITTED (default) is fine as well
- jmxStatistics we can enable this, but will require a name

I think I'll write a very short one:
- enable jmsStats
- define at least an additional cache to be used by Lucene DirectoryProvider (actually, to share the cachemanager we should find a way to pass the instance over to the DirectoryProvider instance)
- enable batching
- change the name of the JGroups configuration file so that it won't conflict with other apps
