Note This parameter is valid only for PolarDB for PostgreSQL clusters and PolarDB for PostgreSQL (Compatible with Oracle)) clusters.	Reader1
Nodes	string	The nodes in the endpoint.	pi-*************,pi-*************
ReadWriteMode	string	The read/write mode. Valid values: ReadWrite: handles read and write requests. Automatic read/write splitting is enabled. ReadOnly: handles read-only requests.	ReadOnly
AddressItems	array<object>	The details of the endpoint.
Address	object	1
VSwitchId	string	The ID of the vSwitch.	vsw-************
PrivateZoneConnectionString	string	The private domain name that is bound to the endpoint.	*..*.com
ConnectionString	string	The endpoint.	********.rwlb.polardb-pg-public.rds.aliyuncs.com
NetType	string	The network type of the endpoint. Valid values: Public Private	Private
Port	string	The port.	1521
VpcInstanceId	string	The ID of the virtual private cloud (VPC) instance. Note This parameter is returned for only PolarDB for MySQL clusters.	pe-*************
VPCId	string	The ID of the VPC.	vpc-***************
IPAddress	string	The IP address.	192.*..**
DBEndpointId	string	The ID of the endpoint.	pe-*************
EndpointConfig	string	The advanced configurations of the endpoint. DistributedTransaction: indicates whether transaction splitting is enabled. Valid values: on off ConsistLevel: the consistency level of sessions. Valid values: 0: eventual consistency. 1: session consistency. 2: global consistency. LoadBalanceStrategy: the load balancing policy that automatically schedules loads. Only load may be returned. MasterAcceptReads: indicates whether the primary node processes read requests. Valid values: on off	{\"DistributedTransaction\":\"off\",\"ConsistLevel\":\"0\",\"LoadBalanceStrategy\":\"load\",\"MasterAcceptReads\":\"on\"}
DBEndpointDescription	string	The name of the endpoint.	test
EndpointType	string	The type of the endpoint. Valid values: Cluster: the default endpoint. Primary: the primary endpoint. Custom: a custom cluster endpoint.	Custom
AutoAddNewNodes	string	Indicates whether new nodes are automatically associated with the default cluster endpoint. Valid values: Enable Disable	Enable
