# MongoDB Consumer
A consumer that allows you to insert records into MongoDB.
## Beans for injection
You can import `MongoDbConsumerConfiguration` in the application and then inject one of the following beans.
`Function<Message<?>, Mono<Void>> mongodbConsumerFunction` - Allows you to subscribe.
`Consumer<Message<?>> mongodbConsumer` - Wraps the function as a Consumer with no-op subscriber.
You can use `mongodbConsumer` or `mongodbConsumerFunction` as a qualifier when injecting.
The return value from the function can be ignored as this is used as a consumer to send records to MongoDB.
## Configuration Options
All configuration properties are prefixed with `mongodb.consumer`.
For more information on the various options available, please see link:src/main/java/org/springframework/cloud/fn/consumer/mongo/MongoDBConsumerProperties.java[MongoDBConsumerProperties].
