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: "In this command, we'll send the test2.mkv file we downloaded to the KVS stream."

A block of code is set as follows:

aws glue create-database --database-input "{\"Name\":\"smartcitybikes\"}"
aws glue create-table --database-name smartcitybikes --table-input file://SmartCityGlueTable.json

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

mediaSource.start();

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

aws rekognition start-stream-processor --name kvsprocessor 

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Once you have entered the appropriate information, all that's left is to click Create signaling channel."
