I was originally on the fence in terms of where additional multi-lang
implementation should live (i.e. do they belong in "external" like the kafka
module), but I'm okay with it as-is. If multi-lang maintenance becomes a
burden, we can always switch to that model later.
If we merge this, we should probably follow up with a heads up to the dev@
and user@ lists that nodejs needs to be installed in order to build.
> Development of multilang protocol in nodejs

> Key: STORM-386
> URL: https://issues.apache.org/jira/browse/STORM-386
> Project: Apache Storm (Incubating)
> Issue Type: New Feature
> Environment: nodejs
> Reporter: Anya Tchernishov
>
> Support nodejs multilang protocol.
> Design considerations:
> - Emit will receive an object (like args and kwargs in python) and a callback
> that is called when task ids list is received.
> self.emit({tuple: [word]}, function(taskIds) {
> self.log(word + ' sent to task ids - ' + taskIds);
> });
> - The following methods will received done method that must be invoked on
> completion (same pattern used by the mocha test framework for async unit
> tests).
> - Internal implementation of emit uses Process.stdout.write without a
> callback since nodejs streams maintain FIFO order (so far, we have not found
> a need for providing a callback).
