Episode notes
From Database Skeptic to Data Engineer
- Weston Pace initially avoided databases, believing they were a "solved problem".
- Years later, he now works on data storage and file formats, driven by real-world data challenges.
Vector Indexes vs. Vector Databases
- In-memory vector indexes offer limited data management capabilities for ML engineers.
- A database with vector columns and indexing capabilities provides more flexibility for filtering and querying data.
Parquet's Random Access Limitation
- Parquet's focus on sequential access makes random access slow, especially for large vector data.
- Lance prioritizes random access to efficiently retrieve specific rows for vector search and training.
