Google Summer of Code 2022

You are viewing an old version of this article. View the current version here.

This year we are again participating in the Google Summer of Code. The MariaDB Foundation believes we are making a better database that remains application compatible with MySQL. We also work on making LGPL connectors (currently C, C++, ODBC, Java, Node.js) and on MariaDB Galera Cluster, which allows you to scale your reads & writes. And we have MariaDB ColumnStore, which is a columnar storage engine, designed to process petabytes of data with real-time response to analytical queries.
