Data Warehouse Types
Product Type Overview
- Standard Data Warehouse GaussDB(DWS) 2.0: a data warehouse service designed for data analysis scenarios. It offers high performance, scalability, reliability, security, and easy O&M for enterprises. With the ability to handle up to 2,048 nodes and 20 petabytes of data, it's a powerful tool for large-scale data analysis. It supports hot and cold data analysis, elastic scaling of storage and computing resources, and on-demand and pay-per-use pricing, providing users with elastic, flexible, and cost-effective experience. It is applicable to converged analysis services that integrate databases, warehouses, marts, and lakes.
- Standard data warehouse GaussDB(DWS) 3.0: a cloud-native data warehouse that uses a cost-effective architecture with decoupled storage and compute. It's designed for OLAP analysis scenarios and offers hot and cold data analysis, elastic scaling of storage and compute resource, unlimited compute power and capacity, and pay-per-use pricing.
- Hybrid data warehouse: a cost-effective solution that goes beyond large-scale data query and analysis. It also offers high-concurrency, high-performance, and low-latency transaction processing capabilities. The data warehouse can be used to process HTAP hybrid loads, and can be deployed in standalone or cluster mode.
- Stream data warehouse: an impressive tool for time series computing and IoT analysis. It is built on the standard data warehouse and can correlate real-time and historical data. Plus, it has an impressive compression ratio of up to 40:1. It can be used for IoT real-time analysis.
- GaussDB(DWS) data warehouses cannot access each other. You can create an OBS foreign table to associate two databases in the same data directory for data query.

- A hybrid data warehouse deployed in standalone mode cannot be changed to the distributed mode. Scaling, logical cluster operations, and resource management are not supported.
- A hybrid data warehouse deployed in standalone mode does not support snapshots, DMS monitoring, or MRS data sources.
- In a hybrid data warehouse deployed in standalone mode, the original syntax for specifying distribution columns will be ignored. Scheduled jobs, the sequence type, HDFS/OBS foreign table import and export, multi-temperature storage, and auto-increment partitioned tables are not supported. OBS foreign table import and export are supported in 8.2.0 and later versions.
- Only DWS 3.0 clusters of 9.0.2 and later versions support the snapshot function.
