I think the Coming Soon info is the most interesting
I copied them below so you don't have to click through Starts at 48min in the video
A lot of new things are coming to ZFS “Soon”™
● Resumable Send
● Replication Record Checksums
● Receive Prefetch
● Compressed ARC
● Persistent L2ARC
● VDEV Removal (Stripe and Mirrors Only)
● Allocation Throttle (Write Bandwidth)
● New Prefetch Algorithms
● More Checksums (SHA512, Skein, Edon-R)
● Compressed Send
● Fast File Cloning
● Dedup Throttle (and Dedicated DDT L2ARC)
● JSON CLI Output
● Replication Rebase (Catch up to a newer snapshot without a common snapshot)
● HA/FO Features (Multi-Modifier Protection)
● Clustered Features
● Tiered Storage (NVMe/SSD -> HDD ->Tape)
● Compatibility with Host-Aware SMR (Shingled Magnetic Recording) Drives
● Per dataset I/O stats
● Per dataset or jail/zone I/O QoS
● Separate VDEVs for Metadata, or Datasets

○ Current Process: Uncompress, Transmit, Compress
○ New Process: Transmit, Uncompress, Compress
○ Since network is usually bottleneck, this achieves better performance. Maybe it could avoid the recompress step as well, if algos are the same
● Channel Programs (Multiple Commands In a Single Atomic Transaction)○ New Process: Transmit, Uncompress, Compress
