BASE

• Emphasis Availability rather than Consistency. A contradict of ACID Normally used in NoSQL

  • Why Availability? DynamoDB Paper says that it's not impossible to build a system that doesn't guarantee 100% Consistency. So we focus on Availability

• BASE stands for:

  • Basic Available
    • Ensure the availability by replicating the data across nodes of the database
  • Soft State
    • Because of lack of immediate consistency. It delegate the responsibility to developers for state
  • Eventually Consistent
    • All reads are still possible (although they might not reflects the reality)
    • The state of the system could change overtime to reach eventually consistent
