DESCRIPTION:
These samples demonstrate how to use the batching API to perform multiple
operations within a single request
USAGE:
python sample_batching.py
Set the environment variables with your own values before running the sample:
1) AZURE_STORAGE_CONNECTION_STRING - the connection string to your storage account
