> Slice gives us an abstraction for using horizontally partitioned databases.
> As of now we use hints to set targets for a particular query if we want it to
> be fired on particular Slices(partitions). This method works fine but we
> need to have something which works from outside the user code as in the case
> of distribution policy. If we have such a way we can externally set targets
> without changing the code. Such targeting should be available for select and
> find.
