GaussDB(DWS) provides client tool packages that match the cluster versions. You can download the desired client tool package on the GaussDB(DWS) management console.
The client tool package contains the following:
- Linux database connection tool gsql and the script for testing sample data
Linux gsql is a Linux command line client running in Linux. It is used to connect to the database in a data warehouse cluster.
The script for testing sample data is used to execute the introductory example.
- Windows gsql
Windows gsql is a command line client running on the Windows OS. It is used to connect to the database in a data warehouse cluster.
Only 8.1.3.101 and later cluster versions can be downloaded from the console.
- GDS tool package
Gauss Data Service (GDS) is a data service tool. You can use the GDS tool to import a data file in a common file system to the GaussDB(DWS) database. The GDS tool package must be installed on the server where the data source file is located. The server where the data source file is located is called a data server or GDS server.
