MongoDB

MongoDB delivers high performance as a NoSQL document database, optimized for speed and efficiency. It uses memory-mapped files for fast data access and supports rich queries with secondary indexes. The document model reduces I/O operations by storing related data together. Features like replication provide data redundancy and failover support, while sharding enables distributed data processing. This performance edge makes MongoDB suitable for real-time applications, IoT platforms, and user-facing systems that demand low latency and rapid data handling at scale, without sacrificing flexibility.
