Simple Primary Key: This is composed of one attribute called the Partition Key. The primary key is used to uniquely identify each item in an Amazon DynamoDB table. Uniquely Identifying Items in a Table with Primary Key In our example, each order item has OrderValue, OrderDate as scalar attributes and products list as a nested type attribute. Most of the attributes are scalar like strings and numbers while some are of nested types like lists, maps, or sets. They are similar to columns in a relational database.Д®ach item has its own attributes. An item is composed of attributes, which are different elements of data for a particular item. Each order is uniquely identified by a combination of customerID and orderID.ДЄ table contains one or more items. This diagram shows the organization of order records placed by a customer in a Order table. Other than the primary key, we do not need to define any additional attributes when creating a table. Like in many databases, a table is the fundamental concept in DynamoDB where we store our data. Here we will only skim through the main concepts that are essential for designing our applications. There is plenty to know about DynamoDB for building a good understanding for which we should refer to the official documentation. Both the keys and the values can be simple or complex objects. A key-value database stores data as a collection of key-value pairs.

If you want to go deeper and learn how to deploy a Spring Boot application to the AWS cloud and how to connect it to cloud services like RDS, Cognito, and SQS, make sure to check out the book Stratospheric - From Zero to Production with Spring Boot and AWS! Example Code Try to search for some native implementation of the dynamo API in your project language which will hold all the data in memory.ДЄlso, a good idea is to make DB access configurable for tests so it will be easy to switch tests between mock / local db / real db.This article gives only a first impression of what you can do with AWS. In my current project I use a custom mock which is a simplified boto API implementation. While tools mentioned above are good to examine the data generated by your application the simplest way to verify your code is to build a set of unit tests.ДynamoDB Local is too slow for unit tests and it is better to use some other dynamo mock. Table prefixesДynamoDB has a single namespace for all tables, so it is better to use table prefixes for different environments and/or different applications. Without the -sharedDb Eclipse will use a file like AKXAX4X6XAFXIXNIXEXA_local.db. To browse an application database start the DynamoDb local with the -sharedDb flag and select вЂlocalвЂ™ region in the AWS regions dropdown.

AWS ExplorerДЄWS Explorer is a toolkit for eclipse which contains the DynamoDb GUI. Without the -sharedDb it will use _us-west-2.db file.ДЄccess key can be set in shell settings, but the region name is hard-coded as us-west-2 (see source in chrome dev tools, /shell/jsrepl/sandbox.js file).
