XML streaming, pipeline parallelizing

[Johann Romefort <ro...@club-internet.fr>]

Hi,

To reformulate my last question in a more cocoon fashion, how can I fire parrallel "generator" steps
in my pipeline and is it possible to stream ( both transforming and serializing) the results to generate
HTML.

Thanks in advance,

Regards,

johann

... and the result will be mix of tags from all different sources? I 
fear even if it could be possible it would make no sense.

You can do whatever you want to do (multiple threads pulling resources) 
in your custom action/generator. First thread corresponding to the first 
part can start generation right away, but results from all other threads 
has to be buffered (say, in a DOM tree) till first part is complete. Or, 
you can start pulling parts simultaneously, and output the results in 
the order as they arrive.

 From coding perspective, ContentAggregator.java is a good start for 
your custom generator.
