Debezium connector for MongoDB

Debezium’s MongoDB connector tracks a MongoDB replica set or a MongoDB sharded cluster for document changes in databases and collections, recording those changes as events in Kafka topics. The connector automatically handles the addition or removal of shards in a sharded cluster, changes in membership of each replica set, elections within each replica set, and awaiting the resolution of communications problems.

How to start

You can run docker-compose with register.sh file.The file use docker-compose-mongodb.yaml and register-mongodb.json files.

cd debezium-mongodb-starter/
./register.sh

Insert document to MongoDB and Test Scenario

You can run commands with docker-compose-mongodb.yaml for insert sample document to mongodb container:

cd debezium-mongodb-starter/

docker-compose -f docker-compose-mongodb.yaml exec mongodb bash -c 'mongo -u debezium -p dbz --authenticationDatabase admin inventory'

After that, you can execute insert query with Immediate CLI.

db.customers.insert([
    { _id : NumberLong("1006"), first_name : 'Kenan', last_name : 'Başdemir', email : 'test@', unique_id : UUID() }
]);

Shut down the cluster

docker-compose -f docker-compose-mongodb.yaml down

How to monitor Kafka

You can access from http://localhost:9000/ web address to web interface.

I used kafdrop for monitoring tool (see: github.com/obsidiandynamics/kafdrop)

How to consume Debezium

You can run sample .Net Core Consumer Project.

cd KafkaConsumerWorker/
dotnet run

To see examples of consumers written in various languages, refer to the specific language sections. For additional examples, including usage of Confluent Cloud, refer to Code Examples for Apache Kafka®.
