Oracle NoSQL is, what bets can be described, as a middle of the road option, based on client server technology that Oracle does so well. It is based on the Berkeley DB edition, with Java. this means it is not able to run Scala and other newer technologies, natively.
The server is based on a number of nodes, the main key of which is incorporated to the server that a record belongs to, by way of a simple hash key. there is only a single master, but multiple replica DB system. one of the problems is that it can take a long time to update the shards- by updating the key-value pairs - though it does not need the shutdown as many other systems are.
One of the better benefits is the way noSQL updates the nodes if the master shard feels - the database if it cannot repair based on a database transaction it will attempt a PAXOS transaction. this means that the database will stay up longer than those which basically fail if the main goes down.
it also makes the normal Oracle mechanisms to provide ACID transactions in cases where noSQL does not.
Try it, if it fits use it. But do not be surprised if there are features which you really need, and are either available only as EE, or not at all.
noSQL is best for casual users. if you have simple practical things to do - then this will do them. but if you are searching for more, you may want to look for other products. it is definitely a tool which will be useful, especially for circumstances where noSQL is not your main forte.
