Thanks @elek for sharing these scripts. I tried a few, and they work fine. I also tried using both read and write scripts at the same time, which needs a few name changes.

I assume one would not use both watchforcommit scripts at the same time. If we did, rule name would need to be unique.

Yes, the chance is low, but let me add the same prefix to here, just to be on the safe side...

I am using https://byteman.jboss.org to debug the performance of spark + teragen with different scripts. Some byteman scripts are already shared by HDDS-4095 or HDDS-342 but it seems to be a good practice to share the newer scripts to make it possible to reproduce performance problems.
For using byteman with Ozone, see this video:
