January 18, 2012, Amazon released Amazondynamodb, a fully managed, high-performance, high-reliability, cost-effective NoSQL database. Dynamodb is ideal for Internet-scale applications.The DYNAMODB database incorporates Amazon's many years of experience in large, non-relational databases and cloud computing. As early as 2007, Amazon published a paper that delves i

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

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 index to support richer queries , you can crea
