As baseline to for use for comparison we will use the time it takes to load the file into a Heap table: BULK INSERT . The durable ones will persist data on disk, the non- durable ones won’t. To enable this option we have to do some housekeeping and assign a fast disk volume for hosting these files. First, alter the database to enable the . CREATE RESOURCE POOL . Once bound we can dynamically change the amount of memory assigned to its pool via the . Every memory- optimized table must have at least one index (either a Range- or Hash index ) which are completely (re- )composed in memory and are never stored on disk. A durable table must have a declared primary key, which could then be supported by the required index. To support a primary key I added an extra row. Looking at the sys.

For the staging of data this definitely a quick win! SSIS Single Bulk Insert into a Non- Durable table. Traditionally SSIS is the fastest way to load a file quickly into SQL Server because SSIS will handle all the data pre- processing so the SQL Server engine can spend its CPU ticks on persisting the data to disk. Will this still be the case when inserting the data into a non- durable table? Below a summary of the tests I ran with SSIS for this post: the SSIS Fastparse option and the . Also the Native OLE DB (SQLOLEDB. SQL Native Client (SQLNCLI1. When you run SSIS and SQL Server side by side,increasing the network packet size isn’t needed. SSIS with Balanced Data Distributor But wait! That is easy to achieve with SSIS; the Balanced Data Distributor will bring just that!
