Sure, I mostly went through this playlist https://www.youtube.com/playlist?list=PLSE8ODhjZXjbohkNBWQs_otTrBTrjyohi https://www.youtube.com/playlist?list=PLSE8ODhjZXjbohkNBWQs_... (I haven't seen all the videos yet). Also some parts of this book https://www.amazon.com/Database-Internals-Deep-Distributed-Systems/dp/1492040347 https://www.amazon.com/Database-Internals-Deep-Distributed-S... were very useful when working on the file structure. I also just recently saw this project https://cstack.github.io/db_tutorial/ https://cstack.github.io/db_tutorial/ which builds a database in C. I have not gone through it but it seems like quite a good resource. For the overall design the CMU playlist is the most helpful.
