Subject [jira] [Commented] (CAMEL-9957) camel-kafka producer sends the message in an async way
Date Sun, 15 May 2016 08:13:12 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-9957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15283810#comment-15283810

Claus Ibsen commented on CAMEL-9957:
------------------------------------

The AsyncProcessor is extending Processor so if you implement AsyncProcessor you also get
the synchronous processor. They are not separated.

The producer is such an example as its both processor / async processor and therefore Camel
routing engine will call favor calling the async processor method. There is no check if the
processor was created from an endpoint that has a synchronous=true option. This option is
not on the endpoint interface, but only an implementation detail on the default endpoint.

Whether it would be an idea for Camel 3.0 to

- separate Processor and AsyncProcessor
- move synchronous as an option to endpoint interface

is something we could consider.

But for 2.x you could either

- create 2 different producer implementations and in the endpoint in the createProducer method
chose either the sync vs async implementation
- use current code
- refactor current code to be a bit better (which I am doing) and then the code is like what
we do in other components that may have a forced synchronous mode.

> CAMEL-9790 made the sync sending, it could cause some trouble when ppl has lots of data
to send.
> We need to provide an async way to send the message to kafka.
