[jira] [Created] (CAMEL-5703) camel-netty - Pool Channels instead
of producers to make producer singleton
Claus Ibsen created CAMEL-5703:
----------------------------------
Summary: camel-netty - Pool Channels instead of producers to make producer singleton
Key: CAMEL-5703
URL: https://issues.apache.org/jira/browse/CAMEL-5703
Project: Camel
Issue Type: Improvement
Components: camel-netty
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Fix For: 2.11.0
We should favor using a light-weight pool for the channel on the producer, so it can be singleton which is the preferred for better scalability.
And use commons-pool etc which has eviction logic built-in. Then channels which becomes idle can be evicted sooner.

Claus Ibsen resolved CAMEL-5703.
--------------------------------
Resolution: Fixed
This change requires a dependency change on camel-netty as commons-pool is used now. This makes backporting harder.

Claus Ibsen updated CAMEL-5703:
-------------------------------
Attachment: after-100.png
after-200.png
before-100.png
before-200.png
before and after screenshots with 100 and 200 clients sending 250.000 messages in request/reply with camel-netty.
With 200 clients the before causes problems by creating to frequent new threads and not cleaning up, which cause memory leak/growth on sustained load. Making high scalability an issue.
Going to backport this to 2.10.x branch
