The JIRA is STORM-386 as mentioned in the description (will fix the title
once the developer is back in the office). We are using it in production
already to migrate nodejs code to storm (low throughput low latency
application).
> 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).
