Zakelly Lan created FLINK-35972: ----------------------------------- Summary: Directly specify key and process runnable in async state execution model Key: FLINK-35972 URL: https://issues.apache.org/jira/browse/FLINK-35972 Project: Flink Issue Type: Sub-task Reporter: Zakelly Lan Assignee: Zakelly Lan
In asynchronous execution model (FLIP-425) for state, the key is managed by the framework and automatically assigned before {{processElement}} or callback running. However in some cases, there should be an internal interface that allows to switch key and start a new process with this key. It is useful when implementing something like mini-batch, which triggers a batch of real logic for gathered elements at one time instead of the {{processElement}} for each element. Additionally, the processing invoked by this interface should have a higher priority than the normal input, as the semantics of this processing method is to continue processing the previously half-processed data. -- This message was sent by Atlassian Jira (v8.20.10#820010)
