Implement alternative behaviour for late tuples
----
> Reemit late tuples in windowed mode
> -----------------------------------
>
> Key: STORM-1873
> URL: https://issues.apache.org/jira/browse/STORM-1873
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Reporter: Balazs Kossovics
>
> Currently late tuples are just logged (and acknowledged in the coming 1.0.2),
> but in our use-case it would be desirable to emit them on a different stream
> than the default.
> I implemented a first version, where every windowed bolt are going to have a
> '_late' stream by default, and component-specific parameter
> (Config.TOPOLOGY_BOLTS_EMIT_LATE_TUPLE) the definer of the bolt could turn on
> or off the emission of the late tuples on this stream.
> One could turn on the emission of late tuples with a builder method like this:
> new MyWindowedBolt()
> .withTimestampField("timestamp")
> .withLateTupleEmission(true)
> .withWindow(
> new BaseWindowedBolt.Duration(1,
> TimeUnit.MINUTES),
> new BaseWindowedBolt.Duration(1,
> TimeUnit.SECONDS)
> );
> What do you think about it?
