Talking and exploring In-Memory topics in SQL Server 2014 has been interesting to me. When I wrote the blog around table variable not being just an In-Memory structure, one of my course listener (SQL Server 2014 Administration New Features) pinged me on twitter to ask, if In-Memory OLTP was really In-Memory? Wouldn’t SQL Server like to swap the data or memory data to pagination file when there is memory pressure? I told them the concept of In-Memory is that data always resides in memory and the reason for a feature name “In-Memory OLTP”. Let us see how we can fix errors related to insufficient system memory.
