MariaDB ColumnStore
You are viewing questions related to 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.
