I am have few SQL Tables when i execute the stored procedures it was taking 52 sec , but i need the stored procedures to be execute less than 10 sec.

I am trying to encrypt the data and storing in the Database . Reading that data makes time

  1. Is there a way to improve the performance.
  2. is there a way to store in azure storage account instead of sql db , will that gain performance. I need an bulk option to read and write the data . do that option is avaliable in the Azure Storage Accounts.
  3. Please provide me the documentation & Guidance to improve the stuff using the Azure Redis cache

    Are you using custom encryption logic to encrypt the data in the table? Is it possible to consider the TDE feature available in the Azure SQL server and move away from your custom encryption?

    Read more about TDE at https://learn.microsoft.com/en-us/azure/azure-sql/database/transparent-data-encryption-tde-overview?view=azuresql&tabs=azure-portal.

    If you cannot change your custom encryption logic, another option is to use a globally distributed Redis Cache with Azure SQL Database to achieve the performance.

    https://devblogs.microsoft.com/azure-sql/maximizing-azure-sql-database-performance-with-a-globally-distributed-redis-write-behind-cache/

    Another alternative approach is to use Azure Cosmos DB, a fast NoSQL and relational database.

    Refer: https://azure.microsoft.com/en-us/products/cosmos-db

    Hope this helps
