> Add option to eagerly deploy channels
> -------------------------------------
>
> Key: FLINK-3232
> URL: https://issues.apache.org/jira/browse/FLINK-3232
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime
> Affects Versions: 0.10.1
> Reporter: Ufuk Celebi
> Assignee: Ufuk Celebi
> Priority: Minor
> Fix For: 1.0.0
>
>
> Intermediate partitions are consumed via input channels. These channels are
> instantiated lazily when the partition producer emits the first record. This
> can lead to higher latencies for the first records passing the pipeline.
> In order to decrease this latency, we can deploy channels eagerly.
> I would like to add this as a flag to the intermediate results of the
> execution graph. On deployment, the task can then deploy the input channels
> as soon as the intermediate stream has been registered at the partition
> manager.
