Subject Re: netty4(-http) producer workerGroup and producerPool
Date Mon, 07 Nov 2016 09:14:06 GMT
Hi Willem,
I just tried sharing the workerpool as per docs of netty4 
( however the class mentioned in 
example ( for sharing of 
worker pools doesn't exist in netty4. I have camel-netty4 as a 
dependency in maven and "netty-all(4.0.34.FINAL)" is present on my 
project classpath as a transitive dependency. The mentioned class exists 
in netty3 as far as I can tell from googling around.

Looks to me docs for netty4 are still pointing to camel-netty 
documentation for example section at least, as the example mention "boss 
and worker thread pools" whereas the options mention bossGroup and 
workerGroup (not pools). You did mentioned that you have updated wiki 
doc, if it's relevant can you please share updated doc link or point me 
in right direction for sharing workerGroup with netty4?
