![History
● Developed by Ericsson in the late 90’s [1,2]
● Initially designed for Telecommunication Applications
Paper: "Design and Modeling of a Parallel Data Server for Telecom Applications" [3]
○ High availability and reliability – downtime less than 30 seconds / year [2]
○ High throughput and linear scalability when adding more servers [2]
● Later Acquired by MySQL
● Incorporated as a Storage Engine
