Scylla is the fastest NoSQL database. Fully compatible with Apache Cassandra, Scylla embraces a shared-nothing approach that increases throughput and storage capacity as much as 10X that of Cassandra. AdGear, AppNexus, CERN, Comcast, Grab, IBM Compose, Intel, Investing.com, MediaMath, Ola Cabs, Samsung and many more leading companies have adopted Scylla to realize order-of-magnitude performance improvements and reduce hardware costs. At ScyllaDB, they carefully apply low-level knowledge to their Big Data technology. Data structures are measured not to cross CPU cache lines, poll-mode drivers are used instead of interrupts, disk accesses are measured for write amplification and caches need to be scan-resistant. They're proud of their very own task scheduler and TCP/IP kernel bypass. They hog the latest C++14 and gcc5.1 for the latest and greatest and dream about commodity non-volatile random access memory. Scylla is available in Open Source, Enterprise, and fully-managed Cloud editions.
