    Hi mwsmoley ,

     

    Thank you for your insights, lbendlin . You are right  this involves not only a trade-off between security and performance but also cost. Keeping Spark pools  warm can become expensive.

     

    To balance these factors, consider the following optimizations.
    1. Reduce Key Vault Calls -  Cache secrets in memory or use environment variables to reduce authentication overhead.

    2. Use Managed Identity -  Switching to Managed Identity can enhance security and performance while simplifying access management.

    3. Optimize Spark Pool Usage -  Schedule workloads efficiently to minimize compute costs and improve resource allocation.

    Hope this helps.
