Thank you for your response. Unfortunately I'm not quite sure the reason that the Voldemort project doesn't push it to the maven repository. There are questions and discussions about the usage of the repository on the Internet, but it seems to me that there is no clear answer for the reason. Or I just have not noticed the existence.
I have several questions about hibernate ogm core. These parts are that particularly I would like you to take a look at. The implementations might be awkward or incorrect. 1. To implement datastore providers for hibernate ogm, there are two code styles. One is from MapBasedDatastoreProvider and the other is from Infinispan and EhCache datastore providers. When we add other datastore providers, which style should we follow ? I've been referencing MapBasedDatastoreProvider from the beginning of my experiment on Hibernate OGM, the implementation followed MapBasedDatastoreProvider. 2. To implement VoldemortDatastoreProvider.setNextValue() method, I was confused a little bit. I originally referenced other datastore and implemented it, but on VoldemortDialectTest.testIsThreadSafe() which tests concurrency on the method, my original implementation<https://gist.github.com/1903794>ran poorly because it required an exclusive lock and datastore access every time the method is called. And then I modified the method and got the current implementation in VoldemortDatastoreProvider. However, it doesn't quite reduce the number of accesses to the underlying datastore as I wanted, but allows concurrency. As a result, I put a flag to store the next valueon the datastore or not. I'm not quite sure if this is the rightimplementation or not. 3. To implement GridDialect.getLockingStrategy() method, the returned object whose type is LockingStratey represents locks on underlying datatore according to the javadoc. How should we implement this method when the underlying datastore doesn't explicitly expose locks as objects ? Looks like that Infinispan exposes some lock objects, so they are instantiated and returned from the method. Voldemort has the concept of optimistic lock exposing a method called voldemort.client.StoreClient.applyUpdate<http://project-voldemort.com/javadoc/all/>and Redis also has the concept exposing a method called watch<http://www.jarvana.com/jarvana/view/redis/clients/jedis/2.0.0/jedis-2.0.0-javadoc.jar%21/index.html>and the description <http://redis.io/topics/transactions#cas> . I use Jedis 2.0.0<https://github.com/xetorthio/jedis>as Redis client. Thank you once again.
