hi Junguk, Welcome to the community!
Yes, Storm Worker processes use Netty for inter-process communication, whether they are on the same node or on different nodes. The LMAX Disruptor is only used for intra-process communication. Just FYI, it didn't always used to be this way, Storm previously used ZeroMQ [1] for communicating between workers, but the system was switched to Netty as part of the Storm project graduating from "incubation" [2]. - Erik [1] http://zeromq.org/ [2] https://incubator.apache.org/incubation/Process_Description.html On Wed, May 25, 2016 at 12:41 AM, Junguk Cho <[email protected]> wrote: > Hi, all. > > I am new to Storm and have a question about messaging passing in storm. > Within one workers, each task use disruptor queue in strom. > > In one node, if there are two workers, does they use Netty for > inter-process communication? > > Thanks, > Junguk >
