I appreciate you willingness to move things forward. I really mean it.

I have talked several times in this thread about collaborating in the
API that you have in mind. I would _very_ much like to have a common
abstraction for ZNS, ZUFS, FDP, and whatever people build on other
protocols. But without tangible patches showing this, we simply cannot
block this anymore.

It is a YCSB workload. You have the scripts here:

    https://github.com/brianfrankcooper/YCSB/blob/master/workloads/workloada

If you have other standard workload you want us to run, let me know and
we will post the results in the list too.

We will post the changes to the L3 placement in RocksDB. I think we can
make them available somewhere for you to test before that. Let me come
back to you on this.
