zhuzhurk opened a new pull request, #19898:
URL: https://github.com/apache/flink/pull/19898
## What is the purpose of the change
This change targets to improve the readability of task names displayed in
logs. The refined task name will be `<job vertex name>
{}(<subtaskIndex>+1/<vertex parallelism>) #<attemptNumber> (graph: <short
ExecutionGraphID>, vertex: <JobVertexID>) `.
It also unifies the task name displayed in logs, for example, currently all
these task name patterns can be seen in the logs of a job:
1. Source: Collection Source (1/1) (3b7bf6af49d4f8a5965b6789933756b7)
2. Source: Collection Source (1/1) (attempt #0) with attempt id
3b7bf6af49d4f8a5965b6789933756b7
3. Source: Collection Source (1/1)#0 (3b7bf6af49d4f8a5965b6789933756b7)
And we would unify all them to be like `Source: Collection Source (1/1) #0
(graph: 6d6f, vertex: bc764cd8ddf7a0cff126f51c16239658)`.
