====== MariaDB ColumnStore Unofficial Documentation Project ======

<note>
**This is a fork of the official ColumnStore documentation in the MariaDB Knowledge Base, maintained by [[https://vettabase.com|Vettabase]]. We created this web space after ColumnStore documentation was taken away from the Knowledge Base.**

See our [[columnstore-documentation-project:manifesto|ColumnStore Documentation Project manifesto]] to find out why we decided to start this documentation.

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.
