MongoDB change data capture: An in-depth guide

Change data capture (CDC) is a technique used to monitor and capture changes in databases like MongoDB, particularly useful for tracking insertions, updates, and deletions in real time. CDC is utilized in various fields and applications due to its ability to ensure systems have access to the latest information and data. Debezium, an open-source platform, allows users to perform CDC with MongoDB by monitoring document-level changes like inserts, updates, and deletes. Another option for performing CDC with MongoDB is using MongoDB CDC handlers, which involve streaming change events from MongoDB to a Kafka topic. Fivetran and Airbyte also support CDC implementation with MongoDB. Debezium can be used in various use cases such as microservices, data warehouses, cache validation, audit logging, and analytics. Implementing CDC with MongoDB involves setting up the necessary tools and configurations to capture and stream real-time changes from databases like MongoDB to a variety of target systems or platforms.
