A data warehouse is a type of database used to store and analyze structured data. Data warehouses excel at aggregating and associating data from diverse sources and mines business value from the data. They play a critical role in business operation decision-making and intelligence analysis.
With the rapid development of database technology and distributed technology, data warehouses evolve towards to distributed databases. The mainstream distributed data warehouse architecture is the massively parallel processing (MPP) architecture, which has the following characteristics:
MPP architecture-based data warehouses feature excellent performance and compatibility (with underlying hardware and upper-layer applications), flexible scalability, and controllable costs, which explains why its popularity among enterprise customers in recent years.
In addition, you can migrate PostgreSQL data to a data warehouse cluster. A data warehouse cluster is a database for OLAP scenarios and the PostgreSQL is a stand-alone database for OLTP scenarios. Therefore, moving the DWS database to a PostgreSQL is not supported.
