Distributed NoSQL databases are designed to manage big data with horizontal scaling, flexibility, and high availability, offering a scalable solution for high-performance applications that can handle large volumes of unstructured or semi-structured data. Unlike traditional SQL databases, which rely on vertical scaling, distributed NoSQL databases process data across horizontally scaled distributed systems, providing a more flexible and efficient solution. They use replication to handle failures without data loss, ensuring high availability and real-time data access. Different types of NoSQL databases, such as key-value, document, column-family, and graph databases, offer unique strengths depending on the specific requirements of the application. When choosing a NoSQL database, businesses must consider factors like performance, scalability, consistency, and cost efficiency. Aerospike is a high-performance distributed NoSQL database that offers low-latency access to data, horizontal scaling, automatic data replication, and Cross Datacenter Replication, making it an ideal choice for large-scale applications requiring real-time data processing at scale.
