Alexey Serbin updated KUDU-1587:
--------------------------------
Status: In Review (was: In Progress)
> Memory-based backpressure is insufficient on seek-bound workloads
> -----------------------------------------------------------------
>
> Key: KUDU-1587
> URL: https://issues.apache.org/jira/browse/KUDU-1587
> Project: Kudu
> Issue Type: Bug
> Components: tserver
> Affects Versions: 0.10.0
> Reporter: Todd Lipcon
> Assignee: Alexey Serbin
> Priority: Critical

> I pushed a uniform random insert workload from a bunch of clients to the
> point that the vast majority of bloom filters no longer fit in buffer cache,
> and the compaction had fallen way behind. Thus, every inserted row turns into
> 40+ seeks (due to non-compact data) and takes 400-500ms. In this kind of
> workload, the current backpressure (based on memory usage) is insufficient to
> prevent ridiculously long queues.
