> When a transaction knows in advance about the set of keys it needs to read, this cache.getAll(k1,k2,..kn) method can bring a some performance improvement:
> 1. all the keys can be fetched from remote nodes in parallel
> 2. keys that map to the same node can be grouped and fetched in the same RPC request
>   
> Note that 1. can be be achieved even at this time by using Cache.getAsync(K) method - that's not as elegant though as it requires the user to write the code the code that waits on the Future objects that are returned.
