Apache Camel tunes its core with new release

Lucy Carey

A souped-up version of the open-source integration framework is available for download now, complete with seventeen new components.

The community around open-source integration framework Apache
Camel is a prolific little hub, and in the space of just four and a
half months, has put together a shiny new release –  Apache
Camel 2.12 – the 53rd Camel version to date.

On the menu for developers is a total of 17 new
components, four new examples, and souped-up performance in simple
or bean languages and general routing. More than three hundred JIRA
tickets have been solved, and a lot of bug swatting and general
fine tuning has taken place. Reflecting the hugely active community
around the platform, around half of these  new components come
courtesy of
external contributors, and
the rest from Camel team developers.

Fulltime Apache Camel committer Claus Ibsen
notes in his

that this is the first release where steps
have been taken to “allow Camel components documentation in the
source code which gets generated and included in the binaries.” He
also writes that “a Camel component can offer endpoint completion
which allows tooling to offer smart completion”, citing the

hawtio web console
as an example of the ways in which this enables functions
like auto completion for JMS queue names, file directory names,
bean names in the registry.

Another notable development is the effective
displacement of the camel-seda by the camel-disruptor, which by
utilising the LMAX Disruptor provides SEDA behaviour in

There have also been some tunings of the
camel-core to improve usability. This includes a reduction of
stack-frames during routing making logging Camel’s stack traces
less clunky, and reducing the need for AsyncCallback callbacks
during routing. Stream caching configuration has become more simple
with StreamCachingStrategy, and New FlexibleAggregationStrategy now
acts as, “a one-stop to perform typical aggregation strategy logic
out-of-the-box: filtering results, storing them in properties,
headers or bodies, as a list, casting results, etc.”

Finally, for camel’s increasingly sociable user
and camel-facebook
have been added to help integrate applications with social
network APIs. And those on the sales side will now be able to
camel-salesforce to
write integration code for platform.
