In-Memory OLTP is integrated with SQL Server to provide a seamless experience in all areas such as development, deployment, manageability, and supportability. A database can contain in-memory as well as disk-based objects.Rows in memory-optimized tables are versioned. This means that each row ...
Row-Level Security in Memory-Optimized Tables Scenarios See Also Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Memory-optimized tables are created using CREATE TABLE (Transact-SQL). Memory-optimized tables are fully durable by default, and, like transactions on (traditional...
Before SQL Server 2016 (13.x), the in-row data size of a memory-optimized table couldn't be longer than 8,060 bytes. However, starting with SQL Server 2016 (13.x), and in Azure SQL Database, you can create a memory-optimized table with multiple large columns (for example, multiple...

Memory-optimized indexes do have a few limitations in SQL Server 2014 that we hope to address in future versions. You do need to consider these limitations when deciding on an indexing strategy for your memory-optimized tables. At most 8 indexes – you cannot ...
In-Memory OLTP introduces memory-optimized tables and natively compiled stored procedures in SQL Server. This article gives an overview of query processing for both memory-optimized tables and natively compiled stored procedures. The document explains how queries on memory-optimized ...
