Using GaussDB(DWS)

Updated on 2025-01-22 GMT+08:00

GaussDB(DWS) is an online data processing database that uses the Huawei Cloud infrastructure to provide scalable, fully-managed, and out-of-the-box analytic database service, freeing you from complex database management and monitoring. It is a native cloud service based on the Huawei converged data warehouse GaussDB, and is fully compatible with the standard ANSI SQL 99 and SQL 2003, as well as the PostgreSQL and Oracle ecosystems. GaussDB(DWS) provides competitive solutions for PB-level big data analysis in various industries.

GaussDB(DWS) provides an easy-to-use management console, allowing you to quickly create clusters and easily manage data warehouses.

Description

Operation Instruction

Making Preparations

-

Before using GaussDB(DWS), you need to apply for a Huawei Cloud account.

Preparations

Create a cluster.

-

Create a cluster before using GaussDB(DWS) to execute data analysis tasks. A GaussDB(DWS) cluster contains nodes in the same subnet. These nodes jointly provide services. During cluster creation, the system creates a default database.

Connect to the cluster.

-

After the GaussDB(DWS) cluster is created, use the SQL client tool or a third-party driver such as JDBC or ODBC to connect to the database in the cluster. You can download the SQL client tool and JDBC/ODBC driver on the Client Connections page of the GaussDB(DWS) console.

Connecting to a GaussDB(DWS) Cluster

Access the database.

-

After connecting to the cluster, you can create and manage databases, manage users and permissions, import and export data, and query and analyze data.

Data Warehouse Service (DWS) Developer Guide

Manage and monitor the cluster.

Cluster management

View the cluster status, modify cluster configurations, add cluster tags, and scale out, restart, and delete the cluster.

GaussDB(DWS) Cluster Management

Snapshot management

Create snapshots to back up and restore the cluster.

Backing Up and Restoring a GaussDB(DWS) Cluster

O&M and monitoring

View the running status and performance of the cluster through monitoring, log auditing, event notification, and resource load management.

Scaling and specification change

  • Expand the capacity of an existing cluster on the console if your service requires additional compute or storage resources.
  • Change the specifications of created clusters on the console.

Cluster upgrade

Cluster 8.1.1 and later versions allow users to deliver cluster upgrade operations on the console.

Upgrading a GaussDB(DWS) Cluster

Resource load management

GaussDB(DWS) provides the resource management function. You can put resources (CPU, memory, I/O, and storage space) into different resource pools, which are isolated from each other.
