I originally wanted to write processes, threads, lightweight threads, goroutine, and coroutine. Why do I list goroutine separately because it is not a coroutine and all translation into coroutine is a concept of stealing, calls coroutine, Which is lighter than a thread. Forget it. Don't worry about it. Today I want to write DynamoDB and record my experiences.

In Dynamodb, database is a collection of table, and table is a collection of item, and item is a collection of attribute. attribute is name-value right. Value can be a single-valued property or a multivalued property (collection). The size of an item cannot exceed 64KB. You get started by understanding this.In addition, DYNAMODB proposes the idea of a two-level i

Tags: style blog http color using IO data arToday we look at Dynamodb's design ideas.Dynamodb primarily wants to achieve high availability (availability) because of the CAP theory, so only consistency is sacrificed, but eventual consistency is achieved. It also wants to achieve the goal of high scalability (scalability), which facilitates horizontal scaling, meaning that high availability and high scalability are the two goals that Dynamodb has to ach
