How the World Has Responded
9
Some common ground
• Scalability
• High Availability
• Schema Flexibility (sort of)
10
5 Dimensions
• Data Model
• Query Model
• Consistency Model
• APIs
• Ecosystem
11
Data Model
Key-Value Wide-Column
Document Graph
12
Data Model - Use Cases
Key-Value Wide-Column
Document Graph
• General Purpose • Basic, static access patterns
• Time series data (wide column)
• Social Networks• Neural Maps• Relationship
13
Query Model
Key-Value Wide-Column
Document Graph
• Rich queries• Indexes
• Basic k/v queries• Rich queries• Relationship analysis
14
Query Model – Use Case
Key-Value Wide-Column
Document Graph
15
Consistency Model
Consistent Eventually Consistent
• Writes are immediately visible
• Data always up to date
• What developers expect
• Writes NOT immediately visible
• Can help read or write throughput
• Risk of stale data• More complexity
16
Consistency Model – Use Case
Consistent Eventually Consistent
• Anything where it’s important to see most up-to-date data, e.g., inventory levels, real-time analytics, collaboration apps
• Anything where it’s not crucial to see most up-to-date data, e.g., logs (high-write), archives (high-read)
17
APIs
• No standard in NoSQL
• Significant variation
• Main options– Idiomatic Drivers– Thrift or RESTful APIs
Java
Python
18
Ecosystem
• Company
• Community
• Partners
