Best Distributed Databases for Huawei Cloud

GaussDB (for MySQL) represents a cutting-edge, enterprise-level distributed database service that is compatible with MySQL. It features a distinct architecture that separates compute and storage, utilizing data functions virtualization (DFV) storage which can automatically scale to accommodate up to 128 TB per database instance. The risk of data loss is essentially eliminated, and it is capable of handling millions of QPS throughputs while supporting cross-AZ deployments. This service effectively merges the high performance and dependability of commercial databases with the adaptability of open-source solutions. By decoupling compute and storage and connecting them via RDMA, along with implementing a "log as database" approach, users can achieve performance levels that are seven times greater than those of traditional open-source databases. Additionally, to enhance read capacity and performance, you can easily integrate up to 15 read replicas for a primary node within just minutes. GaussDB (for MySQL) ensures full compatibility with MySQL, allowing for a smooth migration of existing MySQL databases without the need for extensive application reconstruction or sharding, making it an ideal choice for businesses looking to upgrade their database systems. Overall, this innovative service provides an efficient solution for modern database management needs.
