       OLE DB Destination is available in the Dataflow task in SSIS, which provides a couple of options to push data into the destination table.

• First one is “Table or view” option, which inserts one row at a time.
• Second is “Table or view fast load” option, which internally uses the bulk insert statement to send data into destination table. It’s always provides better performance compared to other options. Once you choose “fast load” option it gives you more control to manage the destination table behavior during various options like Keep identity, Keep nulls, Table lock and Check Constraints.
