As customers' businesses grow and their data volume keeps increasing, there are more and more business systems and business logic becomes more and more complicated. At this time, sharding is a must for a conventional online database. However, the sharded architecture cannot meet the needs of correlation statistics and real-time analysis. Then, the products of real-time data warehouse came into being. Due to the complexity and high cost of real-time data warehouse, not all enterprises need to build a whole set of ecological links. OceanBase's HTAP model was born for this purpose. By using one set of engine, it supports high concurrent online throughput and provides real-time online analysis capabilities for massive data, empowering enterprises to improve their working efficiency and innovate continuously.
