Yu Chen resolved FLINK-33325.
-----------------------------
Release Note:
Since Flink 1.19, we support profiling the JobManager/TaskManager process
interactively with
[async-profiler](https://github.com/async-profiler/async-profiler) via the
Flink Web UI, which allows users to create a profiling instance with arbitrary
intervals and event modes, e.g ITIMER, CPU, Lock, Wall-Clock and Allocation.
Flink users can complete the profiling submission and result export via Flink
Web UI conveniently.
For example,
- First, users should find out the candidate TaskManager/JobManager with
performance bottleneck for profiling, and switch to the corresponding
TaskManager/JobManager page (profiler tab).
- Users can submit a profiling instance with a specified period and mode by
simply clicking on the button `Create Profiling Instance`. (The description of
the profiling mode will be shown when hovering over the corresponding mode.)
- Once the profiling instance is complete, the user can easily download the
interactive HTML file by clicking on the link.
