broadcast keyword

This ia an construct used inside a route based on enterprise integration patterns. It routes the same message to more than one service in parallel.

It is used within the flow definition of a "route" and currently must be the final statement in a route definition

Syntax

...
   broadcast do
      route to "endpoint x"  # occurs two or more times
   end
...

Nesting

each "route" inside the broadcast receives the same message in parallel. A route keyword is used to allow for further nesting of statements.

The route inside the broadcast can be a code block to define a nested flow.
   broadcast do
      route do
         to "filterInBranch1"  # filter
         to "branch1endpoint"  # final provider endoint
      end
      route do
         to "filterInBranch2"  # filter
         to "branch2endpoint"  # final provider endoint
      end
   end

in effect statements can be nested recursively inside code blocks.

IFL enhancements to consider

• What would it mean to allow for further instructions after a "broadcast"? Would it pipe the input that did flow into the broadcast to the following instruction, sequentially after the broadcast completed?
• Should we add an aggregate keyword to join multiple responses before continuing?
• What other enterprise integration patterns constructs should make it into the language?
