Open-source NoSQL database that runs on top of HDFS and is designed for random, real-time read/write access to very large tables — think hundreds of millions of rows with billions of cells. Unlike traditional SQL databases that are optimized for complex queries, HBase is built for ultra-fast lookups by a single row key, making it ideal for applications that need to fetch or update individual records instantly within a massive dataset.
A telecommunications company stores call-detail records for billions of calls in HBase, allowing customer-service agents to pull up any individual call record in milliseconds even though the total dataset spans petabytes.
These services are similar to HBase in that they provide NoSQL database solutions optimized for high-speed read and write operations on large datasets. Each service has unique features and integrations with their respective cloud platforms.
