ApsaraDB for HBase:Manage namespaces

Last Updated:Feb 23, 2024

Namespaces in Apsara DB for HBase are defined as logical groups of tables. Different namespaces can store tables that have the same name. Apsara DB for HBase provides a default namespace. If you do not specify a namespace, the default namespace is used. This topic describes how to use Lindorm Insight to manage namespaces.

Prerequisites

You are logged on to Lindorm Insight of your cluster. For more information, see Log on to Lindorm Insight.

Create a namespace

  1. In the left-side navigation pane of the cluster management system, choose Data Manager > Namespace Manager. By default, all namespaces of the current instance are displayed.
