> As discussed in CASSANDRA-9318, load shedding currently provides very few guarantees
and is not employed at every stage of the pipeline. It is relatively simple to impose bounds
on the number of items in a pipeline stage, along with the age of the items (as we currently
impose). We should also ensure that the predicates are imposed on addition to a pipeline stage,
not removal (as in the mutation/read stage case), since this does not prevent dangerous build
up of outstanding tasks when outlier (or buggy) tasks arrive together (and block processing).
