Recommandations when using podman on ZFS

[knacky34]

Hello,
I've been using Podman since a few years now on a private server which uses ZFS as root filesystem.

The documentations never talks about ZFS storage driver (only docker docs do). And, in some issues about ZFS, maintainers told that zfs driver is not actively developed/supported, and people should go with overlayfs.

I'm wondering if I should migrate from zfs storage driver to overlayfs?
What impact on performance it could have?
And, if there are configurations to apply to ensure podman and ZFS works well together?

Thanks,
