Connection and Port Description for Incremental Synchronization from GaussDB
During incremental synchronization from GaussDB, ensure that two types of connections are available: common connections and replication connections. Common connections are used for data query, and replication connections are used for logical replication.
To ensure normal connection and synchronization, ensure that the database connection is enabled. For details about the configuration method, see Configuring Remote Connection to a GaussDB Database. Then, ensure that the common connection ports and replication connection ports are enabled in the security group and firewall policies.
The replication connection port of a primary/standby GaussDB instance is the common connection port plus 1. Distributed GaussDB connections include CN connections and DN connections. The corresponding replication connection port is the common connection port plus 1.
