Biao Liu created FLINK-13101: -------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
