Hi Wencong Thanks for driving the discussion, +1 for the proposal. I left two minor questions/suggestions:
1. Is the getTaskNameWithIndexAndAttemptNumber method a bit redundant? It can be replaced by getTaskName + getTaskIndex + getAttemptNumber. 2. I think it would be better if we can explicitly specify the alternative (based on TaskInfo/JobInfo) for each deprecated method Best, Lijie Wencong Liu <liuwencle...@163.com> 于2023年11月30日周四 14:50写道： > Hi devs, > > I would like to start a discussion on FLIP-382: Unify the Provision > of Diverse Metadata for Context-like APIs [1]. > > In the Flink project, the context-like APIs are interfaces annotated by > @Public and supply runtime metadata and functionalities to its modules and > components.
