The new In-Memory OLTP feature in SQL Server 2014 greatly optimizes the performance of certain OLTP applications. By using the new memory-optimized tables you can speed up data access, in particular in concurrency situations, due to the lock- and latch-free architecture of the In-Memory OLTP Engine. This means that applications which suffer from a lot Read more
The memory-optimized tables are backed up as part of regular database backups so you don’t need to do anything special to manage backups on databases with memory-optimized tables. Like for disk-based tables, the CHECKSUM of data/delta files is validated as part of database backup to proactively detect any storage corruption. However, as described in the Read more
With the In-Memory OLTP feature in SQL Server 2014 we introduce two new types of indexes for memory-optimized tables: the memory-optimized NONCLUSTERED indexes, and the memory-optimized HASH indexes. Memory-optimized NONCLUSTERED indexes behave similar to traditional NONCLUSTERED indexes from an application point-of-view. The main difference being that memory-optimized indexes are always covering (i.e. all columns are Read more
In the previous blog Merge Operations, we described that how a CFP transitions across various stages in its life cycle. In this blog, we will walk through an actual example to show the state transition. Note, some of the states shown for CFPs are only visible in RTM bits (not in CTP2) but internally the Read more
In the Storage Allocation and Management for Memory-Optimized Tables, we had briefly touched upon the Merge operation. This blog describes Merge operation in detail. We also recommend you to refer to implementing durability for memory-optimized tables for a good understanding of data/delta files and CFPs The metadata of all Checkpoint File Pairs (i.e. CFP) that Read more
