Database Course Recommendation
- Consider Andy Pavlo's database course if you have a software engineering background and want to get into database engineering.
- The course, while dense, offers a deep dive into database internals and a supportive Discord community.
Vector Databases as Indexes
- Vector databases, often associated with AI, are fundamentally data stores with specialized indexes for approximate nearest neighbor searches.
- Relational databases have quickly adopted vector indexes, suggesting the core architecture isn't radically different.
Columnar vs. Row-Oriented Storage
- OLTP systems prioritize row-oriented storage for fast single-record lookups, while OLAP systems use columnar storage for efficient aggregations.
- Columnar storage also enables better compression and encoding, leading to significant performance gains in analytics.
