ADFS, Apple's upcoming file system, was announced at WWDC 2016, and though it may not be as flashy as the Messages enhancements or Siri for apps, it was certainly very important in its own right. Now, programmer Adam Leventhal has gone into detail on on the system, including features such as encryption, snapshots, and performance.
From Leventhal's blog:
APFS first and foremost pays down the unsustainable technical debt that Apple has been carrying in HFS+. (In 2001 ZFS grew from a similar need where UFS had been evolved since 1977.) It unifies the multifarious forks. It introduces the expected features. In general it first brings the derelict building up to code.
It's a very interesting and wide-ranging look at APFS, which is currently in developer preview as part of macOS Sierra. The company plans to make APFS the files system for all of its products, and it is set to ship at some point in 2017.
