Kubernetes initially did not include direct support for stateful services like databases. However, the development of Kubernetes Operators and PersistentVolume support has made it easier to use databases with microservices. NewSQL databases, such as SingleStore, can provide data services to multiple microservices implementations in a manageable way, simplifying the overall architecture and boosting performance. These databases offer features like speed, scalability, SQL support, multiple data types, transactions, analytics, and cloud-native capabilities that are beneficial for microservices environments. SingleStore is a solid candidate for use as a shared relational database for microservices applications, allowing specific services to use local databases while leveraging the benefits of a centralized database for complex operations.
