What is the difference between OLE DB Destinationand SQL Server destination?
SQL Server Destination requires that ETL server and a destination server are the same (not always preferred) OLE DB Destination allows performance optimization by calibrating batch and max commit size. OLE DB Destination allows developers to choose from several data access modes (BULK INSERT is not always needed)
What is OLE DB Destination in SSIS?
The OLE DB destination loads data into a variety of OLE DB-compliant databases using a database table or view or an SQL command. For example, the OLE DB source can load data into tables in Microsoft Office Access and SQL Server databases.
What is maximum insert commit size SSIS?
The default value of the Maximum insert commit size is 2147483647, the largest value a 4 byte INT will hold.
What’s the point of SSIs data flow data access mode?
Under “Data access mode” in in the OLE DB destination editor, it defaults to “table or view” rather than “table or view – fast load”. What is the difference; the only discernible difference I can perceive is that the fast load transfers the data much faster.
Why does SSIs use table or view in OLE DB destination?
Now the question arises where one of the SSIS packages that loads to the DW uses Table or View data access mode in the OLE DB destination. From my understanding, this is in order to pick up the error rows which it inserts (error constraint) into an error records table.
When to use Fast-Load vs fast-access in OLE DB?
Fast-load data access mode allows one to specify the batch rows and the commit size when inserting to destination. For example, inserting 5 million records would take just over 2 minutes. Now the question arises where one of the SSIS packages that loads to the DW uses Table or View data access mode in the OLE DB destination.
What’s the point of OLE DB data access?
The OLE DB Destination Component’s Data Access Modes comes in two flavors – fast and non-fast. Fast, either “table or view – fast load” or “table or view name variable – fast load” means that data will be loaded in a set-based fashion.
