The MongoDB Go Driver is a pure Go package that allows applications to connect to MongoDB, execute commands, and operations. It implements the MongoDB Wire Protocol and supports MongoDB 3.2 and above, making it suitable for all supported database operations. The driver provides Spec Compliant APIs and functionality, as well as support for the latest MongoDB features like multi-document ACID transactions and logical sessions. To use the driver, developers can review the documentation and examples or follow a tutorial to get started. Migrating from community drivers like mgo requires assessing size and impact of changes, locating code points for migration, using Extended JSON, testing, and making general changes such as updating connection strings, BSON types, and using mongo.Client instead of session.Run(). Additionally, developers need to consider CRUD changes, config changes, and ongoing development. The MongoDB Go Driver is under active development, and developers can file requests for missing features or issues they discover during migration.
