B-tree vs B+ tree in Database Systems
In this episode of the backend engineering show I'll discuss the difference between b-tree and b+tree why they were invented, what problems do they solve, and the advantages and disadvantages of both. I'll also discuss the limitation of implementing b-tree over b+tree and how Discord ran into a memory limitation using b-tree Mongo.
