MariaDB ColumnStore

MariaDB ColumnStore is a columnar storage engine that utilizes a massively parallel distributed data architecture. It's a columnar storage system built by porting InfiniDB 4.6.7 to MariaDB, and released under the GPL license.

From MariaDB 10.5.4, it is available as a storage engine for MariaDB Server. Before then, it is only available as a separate download.

MariaDB ColumnStore is designed for big data scaling to process petabytes of data, linear scalability and exceptional performance with real-time response to analytical queries. It leverages the I/O benefits of columnar storage, compression, just-in-time projection, and horizontal and vertical partitioning to deliver tremendous performance when analyzing large data sets.

Release notes and other documentation for ColumnStore is also available in the Enterprise docs section of the MariaDB website. For example:
