# Aurora PostgreSQL Data Source Configuration Guide

## Overview

Amazon Aurora PostgreSQL is a cloud-native relational database compatible with PostgreSQL, offering high performance, scalability, and advanced security features. By configuring the Aurora PostgreSQL data source, you can achieve efficient data synchronization and analysis, meeting enterprise-level data management needs.

## Parameter Configuration

When configuring the Aurora PostgreSQL data source, you need to provide the following information to ensure a successful connection to the Aurora PostgreSQL database:

* **Data Source Name**: Specify a unique and easily recognizable name for your Aurora PostgreSQL data source.
* **JDBC Connection URL**: Provide the JDBC connection URL of the Aurora PostgreSQL database, usually in the format `jdbc:postgresql://host:port/database`. For example, `jdbc:postgresql://aurora-postgresql-host:5432/mydatabase`.
* **Username**: Enter the username used to connect to the Aurora PostgreSQL database.
* **Password**: Provide the database password corresponding to the username.
* **Schema**: Specify the default schema to connect to, such as `public` or any other schema you need to use.
* **Data Source Description**: (Optional) Add descriptive information for the data source to help you or other administrators understand the purpose or characteristics of the data source.

## Connection Configuration

In terms of connection configuration, you can choose one of the following connection methods:

* **Direct Connection**: Ensure that the connection information you entered is accessible over the public network. If the source has an IP access whitelist enabled, make sure the outbound IP address of the data integration service has been added to the whitelist. For specific IP addresses, please contact technical support.
* **Via SSH Tunnel**: To enhance security, you can choose to connect to Aurora PostgreSQL via an SSH tunnel. Enable this option and provide the following SSH tunnel-related configuration information:
  * **SSH Server Address**: Provide the IP address or domain name of the SSH server.
  * **SSH Port**: Specify the port number the SSH server listens to, usually `22`.
  * **Username**: Provide the login username for the SSH server.
  * **Password**: Provide the password corresponding to the SSH server login username.

## Notes

* Ensure that all provided connection information is accurate and that the Aurora PostgreSQL service is accessible.
* Protect your database credentials and SSH credentials to avoid leakage to unauthorized personnel.
* Regularly check and update your data source configuration to adapt to changes in the database structure or new security requirements.
* Monitor the running status of data synchronization tasks to promptly identify and resolve any potential issues.

After the configuration is complete, you can select this Aurora PostgreSQL data source in data synchronization tasks to perform data import or export operations. Connecting via SSH tunnel can enhance the security of data transmission, especially when handling sensitive data. The direct connection method provides a more straightforward data transmission path.
