We are the team behind Scylla, the open source drop-in replacement for Apache Cassandra with lightning fast throughput and ultra-low latency.

The team behind Scylla designed and developed the KVM hypervisor, the default hypervisor in many cloud computing environments, including Google Compute Engine and OpenStack.

At ScyllaDB, we carefully apply low-level knowledge to our Big Data technology. Data structures are measured to not cross CPU cachelines, poll-mode drivers are used instead of interrupts, disk accesses are measured for write amplification, and caches need to be scan-resistant. We’re proud of our very own task scheduler and TCP/IP kernel bypass. We hog the latest C++14 and gcc5.1 for latest and greatest, and dream about commodity non-volatile random-access memory.
