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: "Execute databricks configure --token in the Azure CLI."

A block of code is set as follows:

from pyspark.ml.evaluation import RegressionEvaluator
regEval = RegressionEvaluator(
 			 predictionCol="predictions", \
			       labelCol="rating", \
			       metricName="mse")
predictedTestDF = alsModel.transform(testDF)
testMse = regEval.evaluate(predictedTestDF)
print('MSE on the test set is {0}'.format(testMse))

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

CREATE TABLE [dbo].[CommonCrawlPartitions](
    [YearAndMonth][varchar](255) NULL,
    [Path] [varchar](255) NULL,
    [UpdatedAt] [Datetime]
)

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: Go to the Azure portal and find Azure Active Directory.
