voldemort.store.StorageEngine
A base storage class which is actually responsible for data persistence. This interface implies all the usual responsibilities of a Store implementation, and in addition
1. The implementation MUST throw an ObsoleteVersionException if the user attempts to put a version which is strictly before an existing version (concurrent is okay)
2. The implementation MUST increment this version number when the value is stored.
3. The implementation MUST contain an ID identifying it as part of the cluster
A hash value can be produced for known subtrees of a StorageEngine @param < K> The type of the key being stored @param < V> The type of the value being stored @param < T> The type of the transforms
