MongoDB Trigger

The MongoDB trigger is used to listen on the actions or events (such as insert, update, and remove) performed on the MongoDB collections.

Note: You cannot use this trigger if you connect to Microsoft Azure Cosmos DB using Tibco Flogo MongoDB connection. This trigger uses the ChangeStream APIs to listen to any changes to the documents in a collection in real time. ChangeStream API is supported in MongoDB from 3.6 and higher versions. However Azure Cosmos DB supports MongoDB 3.4 version only.

Trigger Settings

The Trigger Settings section has the following fields:

Field Description
Connection Select the MongoDB connection.

Handler Settings

The Handler Settings section has the following fields:

Field Description
Database Name Name of the database that you want to connect in the MongoDB instance.
Collection Select a collection which you want to listen to. If this field is empty, then the trigger listens to all the collections in the Database.

Listen for Update Event Select to listen to the update event.
Listen for Remove Event Select to listen to the remove event.
