Raul Kripalani commented on CAMEL-6648:
---------------------------------------
Hi [~jhm],
I checked out the implementation and IMHO we should go for a second iteration
with a slightly different approach.
A ProducerTemplate instance is designed to be a long-term, thread-safe object:
created once in the application lifetime and reused thereon. However, if I
understood properly, this implementation relies on creating a new
ProducerTemplate for each Exchange sent, which may cause unnecessary overhead.
Rather than creating a builder pattern for the ProducerTemplate (PT), I'd
rather us focus on providing "fluency" for creating and dispatching new
interactions around an existing PT:
- New FluentProducerTemplate class which wraps a ProducerTemplate inside.
- The implementation is stateless => the newExchange() method returns a new
FluentProducerTemplateInteractionBuilder object extending ExchangeBuilder.
- asyncStyle, dispatchInOut, dispatchInOnly, etc. methods invoke the
appropriate send/request/sendAsync methods in the wrapped PT.
What do you think? I already started working on this, but please do let me know
if you'd like to give it a go yourself.
Regards,
Raúl.
