targetClass

public CreateDBNodesRequest.DBNode.Builder targetClass(String targetClass)

The specifications of the read-only node that you want to add, which must be the same as the specifications of the existing nodes. For more information, see the following topics:

* PolarDB for MySQL: [Specifications of compute nodes](~~102542~~) * PolarDB for PostgreSQL (Compatible with Oracle): [Specifications of compute nodes](~~207921~~) * PolarDB for PostgreSQL: [Specifications of compute nodes](~~209380~~) >- You need to specify either DBNode.N.ZoneId or DBNode.N.TargetClass. N is an integer that starts from 1. The maximum value of N is equal to 16 minus the number of existing nodes. >- You can add multiple read-only nodes at the same time only to PolarDB for MySQL clusters, which can contain up to of 15 read-only nodes. >- This parameter is required for PolarDB for PostgreSQL (Compatible with Oracle) clusters or PolarDB for PostgreSQL clusters. This parameter is optional for PolarDB for MySQL clusters.

zoneId

public CreateDBNodesRequest.DBNode.Builder zoneId(String zoneId)

The zone ID of the node that you want to add, which must be the same as the zone ID of existing nodes. You can call the [DescribeRegions](~~98041~~) operation to query the IDs of zones.
