Conventions used

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

Code in text: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "And, finally, query from the star schema tables. Here is a sample query to get a list of all those customers whose end location was 'San Jose'."

A block of code is set as follows:

SELECT trip.[tripId], customer.[name] FROM 
dbo.FactTrips AS trip
JOIN dbo.DimCustomer AS customer
ON trip.[customerId] = customer.[customerId] 
WHERE trip.[endLocation] = 'San Jose';

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

df = spark.createDataFrame(data= driverData, schema = columnNames)
df.write.partitionBy("gender","salary")..parquet("abfss://path/to/output/")

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

az vm extension set \
  --resource-group <YOUR_RESOURCE_GROUP> \
  --vm-name <VM_NAME> \
  --name OmsAgentForLinux \
  --publisher Microsoft.EnterpriseCloud.Monitoring \
  --protected-settings '{"workspaceKey":"<YOUR_WORKSPACE_KEY>"}' \
  --settings '{"workspaceId":"<YOUR_WORKSPACE_ID>"}'

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "You can see that the data in the top table is distributed horizontally based on the Trip ID range."
