            Hello, I am Rajat Baxi, I have taken courses on Regression analysis, Programming in C/C++, and SQL. I would love to work on this project and already have MariaDB on my system. I would be grateful if anyone could guide me on how to start resolving this issue?

            Hey Rajatino16! I see you're interested in this task for GSoC 2021, thanks and sorry I totally missed your comment here. Can we please move this discussion on MariaDB Zulip? We will be in closer contact there and we won't end up in a situation like this where you ask a question and nobody sees it. Please tag my name in Zulip chat to discuss this further if you're still interested.
