In this episode, we cover the following topics:

• In this new series, we are discussing database consistency models explained in three acts. This episode is "Act III: Eventual consistency saves the web (circa early 2000s)".
• We explain eventual consistency and the motivation behind the philosophy.
• The BASE acronym stands for three key properties of a distributed system that utilizes eventual consistency. We define and explain these BASE attributes:
• Basically available
• Soft state
• Eventual consistency
• We share the story of Werner Vogel's keynote at re:Invent 2018, where he outlined the reasons why DynamoDB was created. In particular, DynamoDB allows for an eventual consistency data model.
• Interestingly, the DynamoDB story closely parallels what happened when Chris was at Microsoft. It just happened at least 6 years earlier.
• We then wrap up everything we have learned about ACID, CAP, and BASE by providing some guidelines on when to choose ACID vs. BASE systems.
