In this video, we deep dive into append-only logs and hash indexes. Two foundational ideas behind modern storage engines and databases.
We start from basic concepts to understand why append-only designs are preferred, how hash indexes work on top of logs, and what trade-offs they introduce.
In the follow-up videos, we’ll build on this foundation by exploring LSM Trees and SSTables, and then move on to B-Trees. Both of which address the key drawbacks of hash indexes.
