:PolarDB-O data source

Background

A PolarDB-O instance is an Oracle-compatible PolarDB for PostgreSQL cluster instance. It supports two types of database accounts: privileged account and standard account. When you use the data transmission service to migrate or synchronize data from a PolarDB-O instance, you must use a privileged account.

When you create a PolarDB-O data source, specify the account created for the PolarDB-O instance here in the Username field.
