Besides the default durable memory-optimized tables, SQL Server also supports non-durable memory-optimized tables, which aren't logged and their data isn't persisted on disk. This means that transactions on these tables don't require any disk IO, but the data is lost if there is a serv...
SQL Server 2014 (12.x) and SQL Server 2016 (13.x) have a limit of 8 indexes per memory-optimized table or table type. Starting with SQL Server 2017 (14.x) and in Azure SQL Database, there is no longer a limit on the number of indexes specific to memory-optimized tables and...
Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Memory-optimized tables require that sufficient memory exist to keep all of the rows and indexes in memory. Because memory is a finite resource, it's important that you understand and manage memory usage on your system. The...
Applies to: SQL Server Azure SQL Database Azure SQL Managed InstanceMemory-optimized tables are created using CREATE TABLE (Transact-SQL).Memory-optimized tables are fully durable by default, and, like transactions on (traditional) disk-based tables, transactions on memory-optimized tables are fully...
Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance This article describes all the aspects of transactions that are specific to memory-optimized tables and natively compiled stored procedures. The transaction isolation levels in SQL Server apply differently to memory-optimized tables ...
Microsoft SQL Server 2017 database, Developer edition. Just updated to latest version (RTM-CU17) (KB4515579) - 14.0.3238.1 (X64). It uses memory optimized tables. When I run a very large stored procedure which deletes many records in many tables, I find that the datab...
