Yu Chen updated FLINK-32186:
----------------------------
Description:
Note that we have introduced a dump link on the backpressure page in
FLINK-29996(Figure 1), which helps to check what are the corresponding subtask
doing more easily.
But we still have to search for the corresponding call stack of the
back-pressured subtask from the whole TaskManager thread dumps, it's not
convenient enough.
Therefore, I would like to trigger the search for the editor automatically
after redirecting from the backpressure tab, which will help to scroll the
thread dumps to the corresponding call stack of the back-pressured subtask (As
shown in Figure 2).
