Apache Arrow JIRA Bot reassigned ARROW-16524:
---------------------------------------------
Assignee: (was: Sasha Krassovsky)
> [C++] Add generic multi-output node
> -----------------------------------
>
> Key: ARROW-16524
> URL: https://issues.apache.org/jira/browse/ARROW-16524
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: C++
> Reporter: Weston Pace
> Priority: Major
>
> A node with multiple outputs is a bit of a tricky thing to create and
> deserving of its own node type. This node would be a pipeline breaker. It
> would need to schedule N tasks for each incoming tasks (potentially N-1 if
> you want to run one of the outputs on the current task). It will need to be
> clever about how it applies backpressure. If either downstream node asks for
> backpressure then the signal should be forwarded.
> Another bonus is that if we can encapsulate this behavior in a generic node
> then we can get rid of the TeeNode because this would become a multi-output
> node where one output is a write node and the other output is the regular
> path.
