List tables using the aws dynamodb list-tables CLI command to verify that our table was created:.I have specified the region even thoughus-east-1` is the default. We also define the maximum expected read and write capacity units per second using theprovisioned-throughput property. We then define a partition key (or hash key) and a sort key (or range key) using thekey-schema property. Here, we define a table named my_table and use the attribute-definitions property to add two fields: id of type string (denoted by S) and ``datetime of type number (denoted byN ). provisioned-throughput 'ReadCapacityUnits=5, WriteCapacityUnits=5' \ key-schema 'AttributeName=id, KeyType=HASH' 'AttributeName=datetime, KeyType=RANGE' \ attribute-definitions 'AttributeName=id, AttributeType=S' 'AttributeName=datetime, AttributeType=N' \ We can create a simple DynamoDB table using the aws dynamodb create-table CLI command as follows:.We will also use CLI commands to check the created table. First, use CLI commands to create the table and then use a CloudFormation template to do the same.

For the complete code files for this article, you can refer to:Ĭreate a simple table, check its properties, update it, and finally delete the table. You are also expected to have a decent understanding of AWS CLI commands, Amazon CloudFormation, and basic database concepts. You need a working AWS account and should have installed and configured the AWS CLI with a profile with the necessary permissions. You can also have an attribute with the same name but different types in different items. You can have a different set of attributes in different items (rows). However, there is no table-level schema in DynamoDB. Unlike most NoSQL databases, DynamoDB also supports consistent reads but with an additional cost.Īttributes in DynamoDB are synonymous with columns, and items are synonymous with rows in a relational database. DynamoDB is a fully managed NoSQL database and you do not have to manage any servers. This is an important part of building quality cloud services.Īmazon DynamoDB is the primary database in AWS for building serverless applications.
