MongoDB has developed an adapter that allows developers to integrate their MongoDB databases with Apache Hadoop, a popular big data processing platform. This integration enables developers to use MongoDB as a real-time data store while shifting large aggregation, batch processing, and ETL workloads to a platform better suited for these tasks. The `mongo-hadoop-streaming-assembly` allows developers to write MapReduce jobs in languages like Python, Ruby, or JavaScript instead of Java, making it easier for developers familiar with MongoDB and dynamic programming languages to leverage the power of Hadoop. With this adapter, developers can process large amounts of data from MongoDB using a variety of programming languages, stream data between MongoDB and Hadoop, and run MapReduce jobs in a more flexible and efficient manner.
