get a single key from the store. Prefer multiGet if you are getting more than one key at a time
Get a set of keys from the store.
Get a set of keys from the store. Important: all keys in the input set are in the resulting map. If the store fails to return a value for a given key, that should be represented by a Future.exception.
Returns a ReadableStore that attempts reads out of the supplied Seq[ReadableStore] in order and returns the first non-exceptional value that satisfies the supplied predicate.
multiGet attempts a full multiGet of the first store, then follows up on missing or failed keys with individual gets to the underlying stores (as failures for each key can happen at different times).
