Use akka jdbc driver maybe.

Per discussions with Tom Pantelis, the possibility of using JDBC with a Java-only database will need packaging discussions with a larger group (TSC or TWS).

For now will just add a comment in akka.conf to describe how to turn on the Java-only implementation of leveldb.

https://git.opendaylight.org/gerrit/#/c/29217/

Automatically choose the journal and snapshot plugin based on the system on which the controller is running. If the journal is set to leveldb only then we should do the auto selection of journal plugin. Otherwise we should leave it as is.

Use leveldbjava where jni is not supported. This should be sufficient.

I don't suppose as "H2 or some pure javadb" you would be interested in using (my) https://github.com/vorburger/MariaDB4j/ project? It's MariaDB (= mysql) binaries packaged in Java - works great, for lots of people out there (several hundreds of dependencies on GitHub alone to it; known to have many more behind firewall corp. users).

Sure. We could provide it as an option where leveldb JNI isn't supported if it performs better than the java-only implementation of leveldb. You'd have to write an akka plugin for it.

CONTROLLER-1884 tracks a pure-Java custom persistence journal implementation. This issue tracks making that journal the default option.
