MongoDB Atlas

The MongoDB Atlas origin reads data from MongoDB Atlas or MongoDB Enterprise Server. For information about supported versions, see Supported Systems and VersionsSupported Systems and Versions in the Data Collector documentation.

The MongoDB Atlas origin reads from capped and uncapped collections. When you configure the origin, you define connection information, such as the connection string and credentials to use. You can specify SSL/TLS properties for an SSL/TLS-enabled MongoDB cluster. You can also use a connectionconnectionconnection to configure the origin.

You configure the database, collection, offset details, and read preference. You can define a custom filter and configure the origin to flatten nested structures.

You can optionally configure advanced options that determine how the origin connects to MongoDB, such as the maximum number of open connections to allow in the connection pool and the cursor type to use for capped connections.

When the stops, the origin notes where it stops reading. When the starts again, the origin continues processing from the last-saved offset by default. You can reset the originreset the originreset the origin to process all available data.

The origin can generate events for an event stream. For more information about dataflow triggers and the event framework, see Dataflow Triggers Overview.
