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.

Where to Start

Please join us on Zulip to mingle with the community. You should also subscribe to [email protected] (this is the main list where we discuss development).

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

List of Tasks

MariaDB Server

• MDEV-30610 Update RocksDB to the latest upstream version ( Full-time project 350h)
  Our version of RocksDB is lagging behind the current upstream and needs to be updated. This isn't a case of simply updating the submodule, there have been significant API changes. It will likely require porting the latest MyRocks code over to the MariaDB storage API.
  • Skills needed: Understanding of C/C++ development. Preferably some experience with the MariaDB or MySQL codebase (but not essential).
    Mentor Andrew Hutchings

• MDEV-17398Spatial (GIS) functions in MariaDB ( Part-time / full-time project (175h - 350h depending on scope) )
  Our GIS functionality is limitted compared to other DBMSes. Given that MariaDB looks to facilitate migration from MySQL, we should be on par. We have a list of functions that are missing in MariaDB compared to MySQL, as described in https://mariadb.com/kb/en/function-differences-between-mariadb-1010-and-mysql-80/.
  Our goal is to have as many of these functions available within MariaDB. Some of the functionality can be ported from MySQL, while others might require implementation from scratch.
  • Skills needed: Understanding of C++ development. Ability to navigate a large codebase (with help from mentor).
    Mentors Anel Husakovic / Vicențiu Ciorbaru

ColumnStore

TO BE ANNOUNCED

Buildbot (CI/CD)

• MDBF-320 Better Grid view for buildbot.mariadb.org (Python / Javascript / Web Dev ( Full-time project 350h)
  Our CI/CD infrastructure uses a recent version of Buildbot. The GRID view plugin that comes with Buildbot is not adequate for our needs. In this project, you will discuss with your mentor as well as other MariaDB developers on how to best improve the User Experience of Buildbot's grid view for what MariaDB Developers needs to accomplish.
  • Skills needed: Understanding of web-dev technologies like Angular, React, and Javascript related libraries. Python may also be required.
    Mentor Vlad Bogolin
