> My contribution in HBASE-28770 contains a bug that is exposed under certain
> conditions. When using AsyncAggregationClient (not AggregationClient), the
> client signals that it can accept partial results. On the server side, this
> triggers AggregateImplementation to check quotas prior to each cell that it
> scans, and return as soon as a throttle is violated, even if the result is
> not complete. The client will sleep and then make a request for the next
> chunk of results.
> However, when AggregateImplementation violates a throttle before finding any
> results at all, it returns a result to the client that says the results are
> empty and complete, so the client should not request any more. Under high
> load, this can happen and lead to the client receiving incomplete results
> that the server says are complete.
