> Topology back pressure using netty transport

> Key: STORM-431
> URL: https://issues.apache.org/jira/browse/STORM-431
> Project: Apache Storm (Incubating)
> Issue Type: Improvement
> Reporter: Sushant Kumar
>
> There are several community threads that talk about automatically managing
> back pressure based on send and receive buffers between the spouts and the
> bolts. This works perfectly in a single worker scenario. Supposedly, it
> doesn't work across multiple workers because of zmq deficiency. Now that
> netty has replaced zmq as a network transport, is it possible to officially
> support buffer lengths as a flow control mechanism in non-reliable topologies
> with high throughput needs?
