Review comment:
@dongjoon-hyun thanks for the review!
I'm wondering if it's possible to include this in `3.3.0`. Here are my two
cents:
1. the community doesn't pay attention to Spark's troubleshooting ability
for a while. If we can deliver this feature earlier, it could give a signal
that the community starts to improve the debuggability and it can attract
others to contribute (earlier).
2. as you may see, this PR aims to reduce the impact on the driver and
introduces useful features (i.e. show AQE plan changes). Such as separate
listener, separate event queue, disk store instead of memory, rest API instead
of UI. I know you have concerns about the disk space. I think it's something we
can resolve.
