Product Advantages

Higher performance gains

Billion-scale data processing. Competitors are often hindered by high distributed costs and inefficient cross-host joins. LongLinDB solves these challenges using breakthrough technologies from the 2.0 database era.

Better engine compatibility

The Hala engine of the StarLink Relational Database Software is built with Java. It offers robust cross-platform compatibility across CPU architectures and operating systems. Leveraging Java's inherent virtualization capabilities, it integrates seamlessly into cloud infrastructure environments that are quantifiable and dynamically scalable.

Better architecture

With a self-developed relational database engine, new data types such as time-series (timestamp sequences), graph, and vector databases can be integrated as plugins within the relational database. By designing corresponding storage models and enhancing the optimizer and executor to leverage these storage capabilities, we create what is known as an ultra-converged database.

Product Deployment

XingHui Lian LongLinBD is a next-generation large-scale, general-purpose, high-speed relational database. It fully supports ANSI SQL standards and interfaces/development frameworks for mainstream programming languages. With its row-column hybrid storage technology, it delivers both OLAP and OLTP capabilities while enabling single-node management and processing of billions of records.
