Oracle MySQL Database Service is a fully managed database service that lets developers quickly develop and deploy secure, cloud native applications using the world’s most popular open source database. MySQL Database Service is the only MySQL cloud service with an integrated, high performance, in-memory query accelerator—HeatWave. It enables customers to run sophisticated analytics directly against their operational MySQL databases—eliminating the need for complex, time-consuming, and expensive data movement and integration with a separate analytics database. HeatWave accelerates MySQL performance by orders of magnitude for analytics and mixed workloads. Optimized for Oracle Cloud Infrastructure (OCI), MySQL Database Service is 100% built, managed, and supported by the OCI and MySQL engineering teams.
