Name a popular NoSQL database used for Big Data storage.

MongoDB is a popular NoSQL database that is widely used for Big Data storage due to its flexible schema design and ability to handle large volumes of data with ease. Unlike traditional relational database management systems, MongoDB stores data in a document-oriented format, which allows for the storage of complex data types and structures. This feature is particularly beneficial in Big Data environments where data types can be varied and unpredictable.

Moreover, MongoDB supports horizontal scaling, meaning it can distribute data across multiple servers easily, which is crucial for handling large datasets typical in Big Data applications. Its rich querying capabilities and ease of integration with various data processing frameworks make it a preferred choice for developers looking to manage and analyze Big Data efficiently. MongoDB also provides robust features such as automatic sharding, replication, and built-in support for powerful aggregation frameworks, which enhance its capabilities in a Big Data landscape.
