>
> To support multiple applications on top of a single Cassandra cluster (and to
> protect against badly behaving clients) having a very simple scheduler for
> client operations would be very beneficial.
> Since all tasks are short lived, a sufficient scheduler would probably only
> need to manage the queue of incoming requests, and weight them based on an
> assigned ID. The ID could be dynamically determined by using ip, userid or
> keyspace for instance, and then each Runnable would be assigned an ID.
