GET event action, useless.

ErrNotReachable is thrown when the API cannot be reached for issuing common store operations.

ErrPreviousNotSpecified is thrown when the previous value is not specified for an atomic operation.

Event represents a event get from watch, Action is 'delete' or 'update' Data is the latest key-value-data of the watched key.

KVPair represents {Key, Value, Lastindex} tuple.

Store represents the backend K/V storage Each store should support every call listed here.

Action is the event type.
