Jark Wu created FLINK-26077: ------------------------------- Summary: Support operators send request to Coordinator and return a response Key: FLINK-26077 URL: https://issues.apache.org/jira/browse/FLINK-26077 Project: Flink Issue Type: New Feature Reporter: Jark Wu
Currently, the communitcation between Operator and Coordiator is sigle-way. That means, after Operator sending a message to Coordiator, it can't wait to get the response message. In some senarios, the Operator may need to retrieve some information stored in the Coordinator. Thus, it would be great if we can have a two-way communication. -- This message was sent by Atlassian Jira (v8.20.1#820001)
