-------------------------------
Component/s: storm-core
> More Intellegent Backpressure
> -----------------------------

> Key: STORM-907
> URL: https://issues.apache.org/jira/browse/STORM-907
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core

> As a follow on to STORM-886 we should look at ways to automatically adjust
> the back-pressure to meet SLAs.
> Using an SLA latency goal for a topology from something like STORM-815 or
> STORM-594 we should be able to come up with a time budget for each stage in a
> DAG. We will have to play games if there are loops in a topology, but it
> should be doable. We could then adjust the budget based off of actual
> latency numbers measured while running. Then throttle the upstream
> bolts/spouts so that the predicted time spent in the downstream queue will be
> under the budget for that stage.
> I see this as a complement to the bang-bang controller from STORM-886
