Castle: Reinventing Storage for Big Data

Location image of event venue


(Unlike the other events on the agenda this week. You do RSVP to this event on the cassandra-nyc page. )

The standard Linux storage stack wasn’t designed for write-heavy big data workloads, nor is it well-suited to modern hardware: large, slow SATA disks, SSDs or many cores.

Acunu's Castle open source project has overhauled from the ground-up the lower layers of the storage stack -- RAID, file system, and the POSIX interface -- for big data workloads, and distributed databases including Apache Cassandra.

Our target is 1 million random inserts per second to disk on a $1,000 commodity box, and we’re nearly there.

Why does it matter to Cassandra users? Castle is the core of the Acunu Data Platform which includes Cassandra and make it deliver up to 100x higher and more predictable performance.

Tim, founder and CEO at Acunu, will give an overview of Castle, how Cassandra maps on to it, and what Cassandra users can do with that.
