Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “You must store binary data encoded in base64 when sending it to DynamoDB.”

A block of code is set as follows:

import boto3
dynamodb = boto3.resource('dynamodb', region_name='eu-west-2')
table = dynamodb.Table('DefinitiveGuide01')
response = table.scan()
items = response['Items']
print(items)

Any command-line input or output is written as follows:

aws dynamodb get-item \
--table-name Employee \
--key '{"LoginAlias": {"S": "janed"}}' \
--endpoint https://dynamodb.eu-west-2.amazonaws.com \
--region eu-west-2

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “As you click on Create replica, you will see a colored balloon at the top of the AWS console that acknowledges that your request to create a replica has been received and work has begun by the DynamoDB service to copy the table data, followed by setting up online replication both ways.”
