Dataflows - Bring Your Own Storage
Hi,
I'm experimenting with Configuring dataflow storage to use Azure Data Lake Gen 2 - Power BI | Microsoft Docs.
In terms of just using a Gen2 data lake for dataflows is there a noticble performance difference between using the Standard and Premium performance tiers?
Hi bcdobbs ,
If your workloads require a low consistent latency and/or require a high number of input output operations per second (IOP), consider using a premium block blob storage account. This type of account makes data available via high-performance hardware. Data is stored on solid-state drives (SSDs) which are optimized for low latency. SSDs provide higher throughput compared to traditional hard drives. The storage costs of premium performance are higher, but transaction costs are lower, so if your workloads execute a large number of transactions, a premium performance block blob account can be economical.
If your storage account is going to be used for analytics, we highly recommend that you use Azure Data Lake Storage Gen2 along with a premium block blob storage account. This combination of using premium block blob storage accounts along with a Data Lake Storage enabled account is referred to as the premium tier for Azure Data Lake Storage.
