SingleStore Kai™ is an API designed to enhance analytics on MongoDB® applications without requiring code changes or data transformations. It allows developers to utilize both MongoDB® and SQL APIs on SingleStore, providing a unified solution for real-time analytics that eliminates the need for multiple data stores. The API supports seamless integration with MongoDB® through Change Data Capture (CDC), enabling data replication without complex tooling or schema definitions. SingleStore Kai leverages a Universal Storage system and a massively parallel processing (MPP) database engine to handle both transactional and analytical workloads, offering significant performance improvements. With its native support for BSON, SingleStore ensures full compatibility with MongoDB® document types, and it provides an interactive terminal via the cloud portal to enhance developer productivity. The platform allows MongoDB® applications to harness the power of SQL for advanced queries, integrate with relational tables, and perform high-speed analytics, making it an attractive option for applications needing fast JSON analytics and scalability. As demonstrated by CanPR, a popular immigration app, transitioning to SingleStore Kai resulted in increased query speeds and eliminated performance bottlenecks, showcasing the API's potential to transform application experiences.
