Hi Charles,

I just created a JIRA[1] for it and will back port the patch CAMEL-8031 to camel-netty4 shortly.

The workaround only work for the netty4-http but not when we use it with
the Rest DSL

This syntax

@Override
public void configure() throws Exception {
// configure to use netty4-http on localhost with the given
port
restConfiguration()
.component("netty4-http")
.host("localhost").port(getPort())
.endpointProperty("nettyHttpBinding", "#mybinding")
.componentProperty("maximumPoolSize","2");

// use the rest DSL to define the rest services
rest("/users/")
.get("{id}/basic")
.route()
.log(">> Thread name : ${threadName}")

will continue to use 16 Threads when we send concurrently 20 messages

Hi Willem,

Thx for your input. I have fixed my problem by setting the parameter on
the component itself

public void configure() throws Exception {

NettyHttpConfiguration nettyConfig = new
NettyHttpConfiguration();
nettyConfig.setMaximumPoolSize(2);
NettyHttpComponent nettyHttp = new NettyHttpComponent();
nettyHttp.setConfiguration(nettyConfig);

getContext().addComponent("netty4-http", nettyHttp);
nettyHttp.start();

// expose a echo service
from("netty4-http:http://localhost:{{port}}/echo")
.log(">> Thread name : ${threadName}")

.transform(body().append(body())).to("mock:result");
}

Only 2 threads are created now

Regards,

Charles

Hi Charles,

You should be able to setup the maximumPoolSize on the Netty4-http
component level due to CAMEL-8031[1].
And the maximumPoolSize only works for consumer side.

Hi,

When I debug this unit test
https://gist.github.com/cmoulliard/123261f7ac2a9d5c719c, the Camel Netty4
HTTP Endpoint is well created with the param "maximumPoolSize=2"

main TRACE [org.apache.camel.impl.DefaultComponent] - Creating endpoint
uri=[netty4-http://http://localhost:26025/echo?maximumPoolSize=2], path=[
http://localhost:26025/echo], parameters=[{maximumPoolSize=2}]

but the number of threads reported by Netty is still bigger than 2

Camel (camel-1) thread #4 - NettyEventExecutorGroup INFO [route1] - >>
Thread name : Camel (camel-1) thread #4 - NettyEventExecutorGroup
Camel (camel-1) thread #3 - NettyEventExecutorGroup INFO [route1] - >>

Do I have to use another param to set the ThreadPool used by
Netty4-http ?
