B+Trees, WAL(write-ahead logging) and LSM trees are core to databases. Most of us look at the interface and talk about SQL vs NoSQL which is useful, but the core database components give the real personality to a database. I created videos on BTrees and WAL long time ago, but

Next video is gonna be on #BloomFilters. Content is finalised. Filled with lots of interesting stuff. Will try to pack it in a ~30min video. It is one of the most interesting and powerful data structure that powers countless databases, caching systems and other large scale

When there's a nail in your head, the immediate problem is the nail, not its colour. Avoid chase the wrong problem 👇 ✅ . 1) Instead of chasing 100% availability, focus on reducing the customer impact and the duration of the impact. 2) Instead of 100% test coverage, focus on.

Don’t take the decisions, you don’t have to. Should we merge these two services?. Should we split this monolith into microservices?. Should we move to gRPC from REST?. …. All these questions are wrong questions if you don’t know the real problem you are solving. Use data.

Things can be stressful at times, but eventually everything becomes sorted. In the long run everything kinda makes sense and becomes a thing to laugh at.

The process that makes writes fast in LSM Trees, i.e. flushing Memtables as new, independent SSTables, creates a significant challenge. Over time, the number of SSTables on disk grows, particularly in the youngest level (L0​), where files can have overlapping key ranges. Without
