ApsaraDB for OceanBase:HBase data source

Background

When you create an instance of ApsaraDB for HBase Performance-enhanced Edition, the root user is created by default. The `root` user has all permissions, including read, write, admin, trash, and system. When you use the data transmission service to migrate data from an instance of ApsaraDB for HBase Performance-enhanced Edition to OBKV, you can create a user and grant permissions to the user as needed.

You need to enter the username in the Username field when you create an HBase data source.
