SQL Server on IoT Edge and Developer Machines – Smaller Footprint

SQL Server According to Bob

SQL Server will ship Azure SQL Database Edge: [link]. For example, Azure SQL Database Edge can already use TSQL Predict Machine Learning (ML) and Column Storage. Partitioning allows SQL Server to scale to the largest systems with record-setting performance. When promoted to a super-latch on a 64 CPU system the memory requirement becomes 32 + (32 *64) = 2080 bytes. However, on smaller systems and VMs the partitioning may not be required to maintain performance.
