What is SelectDB?

SelectDB is a cutting-edge data warehouse that utilizes Apache Doris, aimed at delivering rapid query analysis on vast real-time datasets. Moving from Clickhouse to Apache Doris enables the decoupling of the data lake, paving the way for an upgraded and more efficient lake warehouse framework. This high-speed OLAP system processes nearly a billion query requests each day, fulfilling various data service requirements across a range of scenarios. To tackle challenges like storage redundancy, resource contention, and the intricacies of data governance and querying, the initial lake warehouse architecture has been overhauled using Apache Doris. By capitalizing on Doris's features for materialized view rewriting and automated services, the system achieves both efficient data querying and flexible data governance approaches. It supports real-time data writing, allowing updates within seconds, and facilitates the synchronization of streaming data from various databases. With a storage engine designed for immediate updates and improvements, it further enhances real-time pre-polymerization of data, leading to better processing efficiency. This integration signifies a remarkable leap forward in the management and utilization of large-scale real-time data, ultimately empowering businesses to make quicker, data-driven decisions. By embracing this technology, organizations can also ensure they remain competitive in an increasingly data-centric landscape.
