NoSQL – 19:56

• What are they?
  • Usually don’t require fixed table structures
  • Usually used to scale horizontally
    • Add more commodity nodes as opposed to adding more resources and using expensive hardware
• Why would you use them?
  • Scalability
  • Performance
  • In certain use cases they are easier to implement
• When would you NOT use them?
  • If you don’t know ahead of time how you are going to query or data
    • Applies mainly to key-value type NoSQL
  • Usually arguments start because people think in terms of RDBMS vs NoSQL. They are usually implemented side by side for difference use cases. It is not an all or nothing.
• CAP Theorem
  • Consistency (all nodes see the same data at the same time)
  • Availability (node failures do not prevent survivors from continuing to operate)
  • Partition tolerance (the system continues to operate despite arbitrary message loss)
  • Cap Theorem says that a system can satisfy two of these but not all three.
