Column-Family Databases

Wide-column stores optimized for massive-scale data warehousing and analytics workloads

What Are Column-Family Databases?

Column-family databases store data in column families rather than rows. Each row can have a different set of columns, providing schema flexibility while maintaining excellent performance for analytical queries.

Inspired by Google's Bigtable, these databases excel at handling petabytes of data across thousands of commodity servers with no single point of failure.
