Hi,

I'm trying to investigate whether to use akka persistence in production 
using java.

I've been looking at https://doc.akka.io/docs/akka/snapshot/persistence.html

And also tried this example : 
https://github.com/akka/akka-samples/tree/2.5/akka-sample-persistence-java

The article refers to (native LevelDB) 
https://github.com/fusesource/leveldbjni while the example refers to (some 
java LevelDB port)  https://github.com/dain/leveldb ... not sure why?

Simply changing to use the native one in the example does not work: 
java.lang.NoClassDefFoundError: org/iq80/leveldb/impl/Iq80DBFactory




Q1: So if I do not need a cluster/failover/replication (or i my want to do 
it myself for example) then can I use LevelDB in production? And if yes - I 
guess it should be the native one?


Q2: Then the article recommends replicated journals. So does anybody use 
akka-persistence-jdbc OR okumin/akka-persistence-sql-async in production 
for example?
Are there any recommendations?
I guess they can be used in java too and not only in scala but please 
correct me if I'm wrong.

Thanks!
(inexperienced akka user)
