Reading the delimited files on Azure blob by using the Distributed File System Custom Wrapper is the easiest way you can define the Azure access credentials in the **“custom core-site.xml”** file to access the data in Azure blob storage. While using a Delimited data source to read the delimited file, you have to define different authentication methods such as OAuth.
Also, make a note that it is best to use the Delimited data source when using the **HTTP Client** as the Data route parameter because the delimited data sources offer a better solution for HTTP/HTTPS access as they include proxy access, SPNEGO authentication, OAuth2, etc.
You can refer to the Knowledge Base article [How to connect to Azure Blob Storage from Denodo](https://community.denodo.com/kb/en/view/document/How%20to%20connect%20to%20Azure%20Blob%20Storage%20from%20Denodo) and the [Denodo Distributed File System Custom Wrapper - User Manual](https://community.denodo.com/docs/html/document/denodoconnects/8.0/en/Denodo%20Distributed%20File%20System%20Custom%20Wrapper%20-%20User%20Manual) for more information.
