How production ready is ZFS on Ubuntu (Debian?) ? Is there any risk of Oracle fighting back open source zfs as for Java with Google and Android ?
ZFS is under the CDDL while Java is not under the CDDL. CDDL is an open-source licence just as the GPL.
But incompatible with the GPL, which mostly explains the current situation of ZFS on Linux.
ZFS is excellent for database development! Create a snapshot before you try something that mess up your data and instantly restore it! If your development database is a few gigabytes, this will save you a lot of time.
True, but you can/could easily do that with LVM snapshots and merges too. We snapshot the databases (copy on write) which is instant, then if we want to roll it back we lvm merge and remount. Everything is pretty instant and it doesn't matter what filesystem you want to use.

Do LVM snapshots still cause massive performance degradation? https://www.nikhef.nl/~dennisvd/lvmcrap.html

Anyone here think that a "ZFS in the cloud" that anyone could inexpensively export a ZFS snapshot (or volume) to would potentially be a business model (offsite backups, etc.)?
Don't get me wrong, I looove ZFS, and from a quick scan this article looks like a good intro to ZFS, particularly for someone familiar with git.
I'm tempted to write an article: Who Needs ZFS When You Got Git, but the title IS the article. Don't get me wrong, I looove ZFS, and from a quick scan this article looks like a good intro to ZFS, particularly for someone familiar with git.

> Notably missing is support for merging, which ZFS does not have direct support for as far as I'm aware. That insight is critical, especially now that we are heading towards Dropbox Infinite, IPFS, Ceph and so many other non-centralized file systems. Syncing is not a solved problem at all yet. Advances can bring the same revolution as 3-way merging did to SCMs, previously dominated by file-locking mechanisms.
