Pros
- • Embedded, serverless architecture — no server to run, just a local directory or object store
- • Built on the Lance columnar format for fast multimodal (text, image, video) workloads
- • Zero-copy versioning and cloud sync make it cheap for local-first and edge use cases
Cons
- • Younger project — APIs and Lance format are still evolving
- • Smaller ecosystem of integrations compared to established vector DBs
- • Distributed/multi-writer scenarios are limited vs server-based databases
