Namespaces are logical groups for tables in Lindorm. Tables in different namespaces can share the same name, which lets you isolate tables by team, environment, or tenant without naming conflicts. Lindorm includes a default namespace — tables with no explicit namespace assigned are placed there automatically.
This topic describes how to create, delete, and manage namespaces in the cluster management system.
Prerequisites
Before you begin, ensure that you have:
Logged on to the cluster management system of your Lindorm instance. For more information, see Log on to the cluster management system.
Create a namespace
In the left-side navigation pane, choose Data Manager > Namespace Manager. All namespaces for the current instance are listed.
Click \+ Add.
In the Add Namespace dialog box, enter a name for the namespace.
Namespace names can contain only letters, digits, hyphens (-), and underscores (_).
Click OK.
Delete a namespace
Before you delete a namespace, delete all tables in it. If any tables remain, the deletion fails.
In the left-side navigation pane, choose Data Manager > Namespace Manager.
Find the namespace you want to delete and click Delete in the Operation column.
Click OK.
Associate a namespace with a group
Associate a namespace with the default group or a group you create. For more information about creating groups, see Group management.
Do not associate a namespace with a group that has no servers. Tables in that namespace will become inaccessible.
In the left-side navigation pane, choose Data Manager > Namespace Manager.
Find the namespace you want to associate and select Bind group in the Operation column.
In the Bind group dialog box, select the Target group.
Click OK.
