----------------------------------------
You can use the instanceof operator or Class.isAssignableFrom() to determine
the type.
> StreamTupleExtractor should allow extracting multiple tuples from a single
> event

> Key: IGNITE-1370
> URL: https://issues.apache.org/jira/browse/IGNITE-1370
> Project: Ignite
> Issue Type: Improvement
> Components: streaming
> Affects Versions: ignite-1.4
> Reporter: Raúl Kripalani
> Assignee: Raúl Kripalani
> Fix For: 1.5
>
>
> Currently the {{StreamTupleExtractor}} interface contains a single method:
> {code}
> public Map.Entry<K, V> extract(T msg);
> {code}
> Which only allows extracting a single Entry from an incoming event.
> In real life, it could be that an event contains multiple entries.
