Version Description

V9.0.2

Release date: November 15, 2023

Matching kernel version: 9.0.2

The cloud-native data warehouse GaussDB(DWS) 3.0 is provided.

V8.2.0

Release date: November 23, 2022

Kernel version: 8.2.0

1. GaussDB(DWS) can access data on OBS by using an agency. You can create a GaussDB(DWS) agency, grant the corresponding permissions to the agency, and bind the agency to an OBS data source you created. In this way, you can access data on OBS by using OBS foreign tables.
2. Workload Management is renamed Resource Management, and its usability is enhanced.
3. Optimized resource pool exception rules. You can configure the data spilled to disk per DN and the average CPU usage per DN.
4. The table diagnosis page is added to DMS to monitor and analyze data table statistics in a cluster. You can view information about tables with skew rate higher than 5%, tables with dirty page rate higher than 50%, or top 50 tables in size.

V8.1.3.200

Release date: November 15, 2022

Kernel version: 8.1.3

1. The resizing function is added. You can adjust the specifications of the current cluster or change the cluster topology.
2. Snapshots can be restored to the current cluster.
3. Snapshot creation can be manually stopped.
4. The database monitoring can show server-level trends.
5. On the node management page, you can modify the alias of a node.
6. Enhanced the features of database kernel version 8.1.3. For details, see .

V8.1.3.101

Release date: August 23, 2022

Kernel version: 8.1.3

1. GaussDB(DWS) supports connection to clusters based on DAS.
