Camel 2.0 Design
This wiki page lists the overall goals of the 2.0 release of Camel. For a detailed view see the Camel 2.0 JIRA roadmap
Main features
- default to using transacted mode along with transacted error handlers CAMEL-866
- improve smart completion of Java & XML DSLs (Java DONE, XML a bit better)
- make more endpoints easily configurable as beans in Spring XML CAMEL-506 IN PROGRESS
- improve the DSL
- get rid of
consumer.
options in favor of the new scheduler DONE - support # notation for URI options to lookup a reference in the bean registry DONE
- consider how we can expose some of the ExpressionBuilder we have in Javs DSL in the XML DSL as well
- get rid of
- solving MEP issues DONE
- using Camel${component}${name} pattern as header keys instead of using package names with dots that isn't likely to be transported by JMS or other transport types
- OSGi sample and wiki documentation DONE
- ServiceMix and Camel sample and wiki documentation DONE
Refactoring of code and internal API changes
- remove the use of generics on Component, Exchange, Producer, Consumer CAMEL-872 CAMEL-507 DONE
- reduce the need to copy exchanges CAMEL-872 (jstrachan|hadrian)
- Dealing with streams and minimizing copy performance (jstrachan|hadrian)
- enhance the Expression/Predicate APIs to allow the required type to be passed in
- remove @deprecated code DONE
- improvement of discovery of class resources in OSGi bundles CAMEL-775 DONE
- cleanup Pipeline, BeanInfo (the algorithm to select right method to invoke by bean component)
- rewrite of the File and FTP component DONE
- support VFS in Camel to reuse code for file transport types such as File, FTP and commons-vfs IN PROGRESS
- onComplete(), onFailure() callbacks to UnitOfWork on a Exchange allowing custom code being executed when a Exchange completes
- reduce package tangling
Other
- UUID generator to be file friendly (eg zapping / and : chars) DONE
Nice to haves
- Model objects toString(), label, shortName and description aligned and usable from Tracer/Visual Tooling etc.
Camel 2.1 Design
Main features
- Much improved OSGi (partly already done )
- Running ServiceMix 4.0 kernel
- More documentation and samples
- Making component/converter discovery use OSGi services when in an OSGi environment
- All of the bootstrap mechanisms (components, endpoints, converters, registry) should be osgi aware
- improve the DSL
- Spring 3.0 support
- Improved JMX
- Dynamic routing using JMX
- Pausing consumers using JMX
- Customization of endpoint options using JMX
- and a lot more
- self document the custom headers used in the endpoints/components CAMEL-228
Camel 2.x Design
- have nice Spring 2 namespace schemas for different endpoints for nicer IDE completion
- pluggable DSL (Hadrian) (Groovy will be able to do this)
