--------------------------------
Summary: Refactor StreamTask to construct final fields
Key: FLINK-16712
URL: https://issues.apache.org/jira/browse/FLINK-16712
Project: Flink
Issue Type: Task
Components: Runtime / Task
Reporter: Zhijiang
Assignee: Zhijiang
Fix For: 1.11.0
At the moment there are four fields initialized in the method of
StreamTask#beforeInvoke, such as `stateBackend`, `checkpointStorage`,
`timerService`, `asyncOperationsThreadPool`.
In general it is suggested to use final fields to get known benefits. So we can
refactor the StreamTask to initialize these fields in the constructor instead.
