How to Query Azure Blob Storage

Azure Blob storage is a feature of Microsoft Azure. Users can store large amounts of unstructured data on Microsoft’s data storage platform. In this case, Blob stands for Binary Large Object and includes objects such as images and multimedia files. This data is called unstructured data because it does not follow a specific data model.

Azure data storage is associated with data lakes and analytics, but Azure Blob storage is more focused on general storage goals. In other words, it contains objects that personal users use to store, such as photos, videos and documents. At the enterprise level, these files, log files, and backup volumes are quite large, so Azure is required.

For example, storing your organization’s blob means that you have a backup of the previous version of the site, its content and images, and that it must be accessible from different locations. Businesses can use Azure data storage to make this hardware easier and faster to access than storing it on a single location server.

In Azure Blob storage, files called blobs (photos, videos, training materials, etc.) are placed in containers that function as directories. These are linked to the storage account. When you create an address to access files in Azure data storage, simply combine the storage account with the location of the blob. The address is in .net format.

Azure Blob storage is Microsoft’s object storage solution for the cloud. Optimized for storing large amounts of unstructured data. Unstructured data is data that does not conform to a specific data model or definition, such as text or binary data.

SQL Azure query

Run SQL queries on Azure SQL Database and copy the results to a table via Azure Blob Storage.
This component is intended for data transfer. Capture data in tables and perform other processing and transformations. The target table should be considered temporary because it is truncated or recreated each time the component is run.

Connect to Azure SQL Database and issue a request. Post the results to Azure Blob Storage objects. Next, create or truncate the target table and run the COPY command to load the Azure Blob Storage object into the table. Finally, clean up the temporary Azure Blob storage object.

With Azure Export, you can use SQL to query event data to express new types of queries, or join other data that already exists in the data environment.

This Azure Blob export provides the following functionality:

  • Hourly, daily or weekly export calendar.
  • Export, analyze and extract the data schema on time.
  •  Clean the data and convert it to JSON or parquet format.
  • Provide a backward compatible AVRO diagram
