Key-Value Stores
- Interface - extremely simple
- Data model
- (key, value) pairs
- Operations: Insert(key, value), Fetch(key), Update(key), Delete(key)
- Implementation - efficiency, scalability, fault-tolerance
- Records distributed to nodes based on key
- Replication
- Single-record trasactions, "eventual consistency".
