We develop Scylla, a Cassandra compatible NoSQL database, at 1MM transactions/sec per server.

At ScyllaDB, we carefully apply low-level knowledge to our Big Data technology. Data structures are measured not to 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.

ScyllaDB, formerly known as Cloudius Systems, is an open source-centric company, led by the originators of the KVM hypervisor and employ superstar virtualization, database, and OS veterans. The ScyllaDB team is behind OSv and Seastar open source projects
