Kx Systems provides an integrated in-memory columnar database and programming system called kdb+ that is optimized for real-time streaming and historical big data analytics. It has been widely adopted in financial services over two decades due to its high performance, low latency, and low total cost of ownership. Kx's technology can process large datasets much faster than traditional databases and supports real-time analytics, ad-hoc queries, and dashboards for applications in industries such as utilities, energy, and telecommunications. A case study example showed how Kx helped a utility process over 300 billion rows of meter data daily with greatly improved performance and availability over their previous system.
