Four years ago ScyllaDB introduced Scylla — a new open-source NoSQL database, compatible with the popular Cassandra but 10 times faster (Slashdot story). Today the project announced support for the DynamoDB API as well. This will allow applications that use Amazon's DynamoDB to be migrated to other public or private clouds — running on Scylla instead of DynamoDB.
Beyond the added choice, large users may also see their cloud bills drastically reduced by moving to Scylla: ScyllaDB reported in the past that the total cost of running Scylla is only one seventh the cost of DynamoDB.

At Cassandra Summit opening today, Avi Kivity and Dor Laor (who had previously written KVM and OSv) announced ScyllaDB — an open-source C++ rewrite of Cassandra, the popular NoSQL database. ScyllaDB claims to achieve a whopping 10 times more throughput per node than the original Java code, with sub-millisecond 99%ile latency. They even measured 1 million transactions per second on a single node. The performance of the new code is attributed to writing it in Seastar — a C++ framework for writing complex asynchronous applications with optimal performance on modern hardware.

Today in CloudOpen in New Orleans, KVM veterans Avi Kivity and Dor Laor revealed their latest venture, a new open-source (BSD license) operating system named OSv. OSv can run existing Linux programs and runtime environments such as a JVM, but unlike Linux, OSv was designed from the ground up to run efficiently on virtual machines. For example, OSv avoids the traditional (but slow) userspace-kernel isolation, as on the cloud VMs normally run a single application. OSv is also much smaller than Linux, and breaks away from tradition by being written in C++11 (the language choice is explained in in this post).
