Scylla is an open source NoSQL database offering the same Cassandra Query Language (CQL) interface as Apache Cassandra, along with the same horizontal scale-out and fault-tolerance characteristics. Implemented from scratch in C++ with a close-to-the-hardware architecture, Scylla delivers 10X the throughput, consistent, low single-digit latencies, and significantly reduces the number of database nodes you require and self-optimizes to dynamic workloads and various hardware combinations. With the release of Scylla Open Source 3.1, we’ve introduced a number of […]
In this article we will explore one IoT/time-series classical scenario in which knowledge of how the cache operates can mean the difference between a fully cached workload that will be fast, and a fully storage-bound workload that will of course perform much worse.
