Google Summer of Code 2026

In 2026, we are again participating in the Google Summer of Code. We, joined with the MariaDB Foundation, believe 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.

Where to Start

Please join us on Zulip to mingle with the community. You should also subscribe to the developers mailing list (this is the main list where we discuss development - there are also other mailing lists).

To improve your chances of being accepted, it is a good idea to submit a pull request with a bug fix to the server.

Also see the List of beginner friendly issues from the MariaDB Issue Tracker.

MariaDB Server

MDEV-28395 LOAD DATA plugins

Full-time project 350h

LOAD DATA INFILE can flexibly load data into a table from CSV-like files accessible by the mariadbdb process. LOAD XML INFILE can do it for XML files. LOAD DATA LOCAL INFILE and LOAD XML LOCAL INFILE can do it with files accessible by the client, but not by the server. But there are requests to support loading more file formats and from other locations, for example, from S3.

This project is to implement support for LOAD plugins and refactor the current LOAD code accordingly. There are two kind of plugins — data parser plugin (CSV-like and XML) and transfer plugin (file and LOCAL). Implementing new plugins is not in the scope of this task, this task is mainly about moving existing code around, creating a possibility for new plugins (like JSON or S3).
