--------------------------------
Summary: Introduce "blocking after chaining off" property of StreamGraph
Key: FLINK-13101
URL:
https://issues.apache.org/jira/browse/FLINK-13101 Project: Flink
Issue Type: Improvement
Components: API / DataStream
Reporter: Biao Liu
Assignee: Biao Liu
Fix For: 1.9.0
The property "blocking after chaining off" means, if there are some stream edges that can not be chained and the shuffle mode of edge is not specified, translate these edges into {{BLOCKING}} result partition type.
The reason of introducing it is to satisfy the requirement of Blink batch planner. Because the current scheduling strategy is a bit simple. It can not support some complex scenarios, like a batch job with resources limited.
To be honest, it's probably a work-around solution. However it's an internal implementation, we can replace it when we are able to support batch job by scheduling strategy.
