This topic describes how to query tenant parameters using the obshell-sdk-go API, including exact query and fuzzy query.
Note
We recommend that you first read through the Quick start with obshell-sdk-go section to understand how to use obshell-sdk-go.
Query specific tenant parameters
Considerations
Ensure that obshell is running normally.
Ensure the tenant already exists and its status is NORMAL.
The node corresponding to the requesting client must be within an initialized cluster.
Sample code
package main
import (
"fmt"
"github.com/oceanbase/obshell-sdk-go/services"
)
func main() {
// Create a client instance with the node address '10.10.10.1' and port 2886.
client, err := services.NewClientWithPassword("10.10.10.1", 2886, "****")
if err != nil {
fmt.Print(err)
return
}
value, err := client.V1().GetTenantParameter("t1", "arbitration_timeout")
if err != nil {
fmt.Print(err)
return
}
fmt.Print(value)
}
Fuzzy query for tenant parameters
Considerations
Ensure that obshell is running normally.
Ensure the tenant already exists and its status is NORMAL.
The node corresponding to the requesting client must be within an initialized cluster.
Sample code
package main
import (
"fmt"
"github.com/oceanbase/obshell-sdk-go/services"
)
func main() {
// Create a client instance with the node address '10.10.10.1' and port 2886.
client, err := services.NewClientWithPassword("10.10.10.1", 2886, "****")
if err != nil {
fmt.Print(err)
return
}
parameter, err := client.V1().GetTenantParameters("t1", "max_partition%")
if err != nil {
fmt.Print(err)
return
}
fmt.Print(parameter)
}
