In TriggerMesh v1.24 we introduced a new MongoDB target. In this post I want to show you how to set it up. This is particularly useful if you want to store messages persistently or hydrate a data lake based on Mongo.
With the TriggerMesh CLI tmctl, you can create a MongoDB target by using the connection string that you will have previously downloaded (containing the username, password and hostname), the database name and the collection name.
Here's what it looks like with a database called tmctl and a collection called demo:
All the parameters that can be used to configure this target can be obtained via tab completion:
tmctl create target mongodb \
--adapterOverrides ((object) Kubernetes object parameters to apply on top of default adapter values.)\
--collection ((*required,string) Define the default (over-writeable at runtime) collection to write new events to.)\
--connectionString ((*required,string/secret) The connection string containing the endpoint for the MongoDB Server and the…)\
--database ((*required,string) Define the default (over-writeable at runtime) database to write new events to.)\
--eventTypes (Event types filter.)\
--help (help for target)\
--name (Optional component name.)\
--source (Event source name.)\
--version (TriggerMesh components version.)
If you want to see all the steps interactively, check out this very short screencast which demonstrates how to build the highly popular integration between a Kafka topic (via a Kafka cluster running in Confluent cloud) and a MongoDB database running on Digital Ocean.
Once you are happy with your local flow you can decide to deploy it on a Kubernetes cluster running TriggerMesh. The MongoDB target API manifest will look like this:
