Apache Kafka and MongoDB are integral components of contemporary data architectures, where Kafka serves as an event streaming platform and MongoDB as a versatile database for large volumes of diverse data. The integration of these systems is facilitated through Kafka Connect, which enables seamless data streaming between external systems and Kafka topics. The MongoDB Connector for Apache Kafka, developed and maintained by MongoDB Inc., allows MongoDB to act as both a source and a sink for Kafka, supporting scenarios such as event-driven architectures and microservices. This connector can be installed via Confluent Hub either automatically or manually, providing flexibility in deployment. The document further illustrates practical use cases of this integration, such as an e-commerce scenario where MongoDB and Kafka are used to manage inventory data and notify systems for reordering products, and another where new user information is propagated across business systems. Additionally, the text touches on MongoDB's leadership transition, with Dev Ittycheria announcing his retirement as CEO by 2025, and Chirantan “CJ” Desai being named as his successor, highlighting Desai's extensive experience and suitability to guide MongoDB through its next phase of growth.
