--- title: DB - MongoDB slug: manufacturing-connect-edge/db-mongodb docTags: createdAt: 2023-12-01T19:35:12.163Z --- Review the [MongoDB Integration Guide](docId\:p148zBzLCmhQj1QizHM43). ## Overview MongoDB integration enables an Edge System to connect with a MongoDB database. ## Supported Versions - MongoDB 2.x - MongoDB 3.2 ## Supported Communication - Outbound (Edge to Database) - Yes - Inbound (Database to Edge) - No ## Configurations | **Variable** | **Detail** | **Required** | | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------ | | Name | Enter a name for the connector | Yes | | Hostname | IP Address or Hostname of MongoDB Server (Must be reachable from the Edge system) | Yes | | Port | MongoDB Server port | Yes | | Username | User name | No | | Password | User password | No | | Auth database | Authentication database name | No | | Auth mechanism | Authentication mechanism (can be one of "SCRAM-SHA-1", "MONGODB-CR", "MONGO-CR", "PLAIN", "MONGODB-X509") | No | | Database | Database name. If database does not exist it is created. | Yes | | Collection | Collection name. If collection does not exist it is created. | Yes | | Show Mapping | Data from a predefined table could be mapped into a custom one. Example: \{"from": "to"} where "from" is a column from predefined table, and "to" is a column from destination table. See [Work with Tables in SQL Connectors (Create Table and Show Mapping)](docId\:FI9mBipRrRIxufdIHwQl9) to learn more. | | | Commit timeout | Transaction commit timeout (ms) | No | | Max transaction size | Maximum number of messages before a transaction is committed regardless of timeout | No | | Throttling limit | Set a limit on the number of outbound messages per second. If sending data to a server that has restrictions on the rate of incoming messages, this ensures that no messages are lost. | No | | Queue mode | Select the sequence of data transfer: FIFO or LIFO. Selecting FIFO (First In First Out) will send the earliest message first. Selecting LIFO (Last In First Out) will send the latest message first. | No | | Persistent storage | If enabled, messages in the outbound queue are stored on disk. If there are interruptions in connection or power loss, messages will be retained and eventually sent when the connection is restored. | No |
