Integrating Atomic IO into Filesystem Transactions - Chris Mason

Sign up or log in to save this to your schedule and see who's attending!

Atomic IO is a new storage feature allowing filesystems to send down writes as a group to the storage device and know the entire group will be written as a single unit, or not at all. This presentation will examine how filesystems can use atomics to improve performance in synchronous workloads. Sample implementations and benchmarks for Btrfs, Ext4 and XFS will be discussed. I'll also cover interfaces for exporting atomics to user level applications.
