What are In-Memory OLTP and Memory Optimized Tables

In-Memory OLTP 

In-Memory OLTP is an in-memory computing technology developed by Microsoft to speedup the performance of transaction processing applications running on SQL Server databases. In-Memory OLTP is built with two core components: memory-optimized tables and natively compiled stored procedures. In-Memory OLTP, also known as 'Hekaton' and 'In-Memory Optimization', which is Microsoft's latest in-memory processing technology of 2014.

In-Memory Tables

It is integrated into SQL Server's Database Engine and which can be used in the similar way as other Database Engine component. In-Memory OLTP originally came with SQL Server 2014 .


Memory-Optimized Tables

Memory-optimized tables are fully durable, like transactions on disk-based tables, transactions on memory-optimized tables are fully ACID compatible . Memory-optimized tables and natively compiled stored procedures support only a subset of Transact-SQL features.

The primary storage for memory-optimized tables is the RAM. Rows in the table are read from and written to memory. A second copy of the table data is maintained on disk, but only for durability purposes.

After connecting to SQL Azure portal when operation started to deployment below errors occurs.

Validation of the schema model for data package failed. Error SQL71562: Error validating element xx.xxx.xx:function .dbo.xxx has an unresolved refrence to object xx.dbo.xxxx external refrences are not supported when creating a package from this platform.



Reason: The reason of the this error was; some functions of project was dependent on master database and only single database was being deploy to SQL Azure. DACFx must block Export when object definitions (views, procedures, etc.) contain external references, as Azure SQL Database does not allow cross-database external references So, this error was coming.

Solution : I suggested him to create those function to locally on local database what…
