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. Castle, an open-source project, is a ground-up overhauling of RAID, file systems, and the POSIX interface. It is released under the GPL and runs as part of the Linux kernel. Our target is 1 million random inserts per second to disk on a $1,000 commodity box, and we’re nearly there. Castle is also the core of the Acunu Data Platform, which delivers up to 100x higher performance for applications written for Cassandra and other tools.
