James Serra announces changes to Azure SQL Data Warehouse:

The changes in Azure SQL DW Compute Optimized Gen2 tier are:

  • 5x query performance via a adaptive caching technology. which takes a blended approach of using remote storage in combination with a fast SSD cache layer (using NVMes) that places data next to compute based on user access patterns and frequency

  • Significant improvement in serving concurrent queries (32 to 128 queries/cluster)

  • Removes limits on columnar data volume to enable unlimited columnar data volume

  • 5 times higher computing power compared to the current generation by leveraging the latest hardware innovations that Azure offers via additional Service Level Objectives (DW7500c, DW10000c, DW15000c and DW30000c)

  • Added Transparent Data Encryption with customer-managed keys

Those are some good improvements.  #2 in particular makes it possible for Azure SQL DW to be useful in a much larger number of environments.
