Summary: Priority in streams
Key: STORM-284
URL: https://issues.apache.org/jira/browse/STORM-284
Project: Apache Storm (Incubating)
Issue Type: Wish
Reporter: Gianmarco De Francisci Morales
When a single bolt has multiple input streams, they both flow into the same
input queue for the bolt. If one of the streams if much faster, the other will
"starve".
This is a big issue when trying to use separate control/data streams in Storm,
where naturally data arrives much faster than control, but control messages are
more important.
A simple way to solve this issue is to declare an optional (class of) priority
when latching a bolt onto a stream. Then keep separate queues in the platform,
one for each priority level, and check them for messages in order.
