This is a follow up on using Tomcat 6 and the CometProcessor interface:
A. From Kris Zyp's post on [http://cometdaily.com/2007/12/10/comet-gazing-scaling/
],
with the Tomcat CometProcessor, connections and threads are
decoupled, so that
the number of connections can can scale independently of the
number of threads.
Schmidt/Javaloggy [http://www.javalobby.org/java/forums/
t92965.html -- 4/5/07] cites tests by
Filip Hanik scaling from 1000 --> 16,000 connections, but some of
the comments (#8, MikeP)
were less than enthusiastic, suggesting that maybe not all 16000
were properly served.
That's a year old. Is there any more up-to-date info available?
Are there any production examples of the Tomcat 6 comet processor
scaling at least this far,
if not up into the 10's of 1,000's ??
B. Zyp [http://cometdaily.com/2007/12/10/comet-gazing-scaling/]
states "... the difficulty of
horizontally scaling... implementing a publish/subscribe type
Comet mechanism on Tomcat that
scales efficiently across multiple machines would require
significant effort to properly route and
distribute messages effectively."
Again, that's a year old What is the status on this? Our target
is to run in a cluster.
C. Besides the chat pseudo-code at http://tomcat.apache.org/tomcat-6.0-doc/aio.html
, are there other available examples?
