Driver Package and Environment Dependency

DDS allows you to perform operations using Java. In this way, you can connect to an instance through an SSL connection or an unencrypted connection. The SSL connection encrypts data and is more secure.

SSL is disabled by default for a new DDS instance. To enable SSL, see Enabling SSL.

Installing the Driver

Click the JAR driver download address to download mongo-java-driver-3.12.9.jar, which provides APIs for accessing DDS DB instances.
To install the driver, see the official guide.

Environment
