On Wednesday 24 June 2020, MariaDB Server 10.5 was released GA. While there are several cool new features included, this first 10.5 blog is about the groundbreaking new component, ColumnStore.
ColumnStore brings data warehousing to the world of MariaDB Server. It’s a columnar storage engine (Wikipedia: Column-oriented DBMS), enabling what is often called HTAP (Wikipedia: Hybrid Transactional/Analytical Processing). The Columnar data type stores data by columns, not by rows, enabling quick analytical reporting over huge data volumes.
The ColumnStore engine is part of MariaDB Server 10.5.
