Connectors & Integrations Discussions about tools for moving data to/from MongoDB and integrating MongoDB into your environment including using MongoDB Connector for BI, Kafka Connector, Spark Connector, and Relational Migrator. Java Frameworks Discussions about developing with MongoDB using Java frameworks such as Spring and Hibernate, as well as ODMs like spring-data-odm and morphia-odm in the Java ecosystem. Drivers Discussions about developing with MongoDB using various programming languages and MongoDB drivers. Python Frameworks Discussions about developing with MongoDB using Python frameworks such as Django and Flask, as well as specific ODMs like PyMODM and MongoEngine in the Python ecosystem. Node.js Frameworks Discussions about developing with MongoDB using Node.js ODMs like mongoose for the backend and next-js for the frontend.
