# ----------------------------------------------------------------------------------------------------------
# Prerequisites -
#
# 1. An Azure Cosmos account -
#    https://docs.microsoft.com/azure/cosmos-db/create-sql-api-python#create-a-database-account
#
# 2. Microsoft Azure Cosmos
#    pip install azure-cosmos>=4.3.0b4
# ----------------------------------------------------------------------------------------------------------
# Sample - demonstrates how to authenticate and use your database account using AAD credentials
# Read more about operations allowed for this authorization method: https://aka.ms/cosmos-native-rbac
# ----------------------------------------------------------------------------------------------------------
# Note:
# This sample creates a Container to your database account.
# Each time a Container is created the account will be billed for 1 hour of usage based on
# the provisioned throughput (RU/s) of that account.
