I would like to update you that azure storage operates on an HTTP-based Request/Response model. When you send a request to Azure Storage, it promptly responds, after which the connection is gracefully closed. Hence, it is not feasible to maintain an open connection to an Azure Storage account, and the implementation of connection pooling is not possible in this context.
The thread below discussed a similar query.
The following article talks about the azure storage rest api. https://learn.microsoft.com/en-us/rest/api/storageservices/
Please do let me know if you have any additional questions with regards to this question.
