Hi,

I listened to the podcast it was interesting.

Gonna throw some questions you may or may not have gotten.

Are special devices like metadata or write-ahead log devices on the roadmap? Or distributed raid / other exotic raid types?

It would be interesting to hear your thoughts on these.

What do you think zfs got right with this and what did they get wrong?

You can do that now via the data_allowed parameter

ZFS did a bunch of stuff right, it's just a much older design; pre-extents, and based on the original Unix filesystem design - filesystem as a database was still unproven at the time.

They were just working incrementally, which for the amount of new features ZFS already had was the smart decision at the time.
