Clearing a file after reading with SSIS. The archive folder is compressed whereas the working folder is uncompressed. We setup a process with our Data Center IT to archive the files in the folders to tape on a regular schedule. This gives us full freedom to retrieve any raw files we have processed while getting them off the SAN without requiring department resources. The Raw File source is used to retrieve raw data that was previously written by the Raw File destination. You can also point the Raw File source to an empty raw file that contains only the columns (metadata-only file). You use the Raw File destination to generate the metadata-only file without having to run the package. SSIS 2008 RAW file viewer. No tags have been added.

High speed data transform Integration Service Integration Services raw file raw file destination raw file reader raw file source SQL Server SSIS High Speed Data Transformation Using Raw Files This post explains a SSIS technique that transforms large volume of data in shorter time by using Raw Files. We use SSIS for our data warehouse and use RAW files all over the place. We extract data from our source system into RAW files (1 file per table). Then during the transform and load stage we take the extracts and upgrade them (schemas change over time) to the most recent version in a temporary folder.

The Raw File source reads raw data from a file. Because the representation of the data is native to the source, the data requires no translation and almost no parsing. This means that the Raw File source can read data more quickly than other sources such as the Flat File and the OLE DB sources.

You can also point the Raw File source to an empty raw file that contains only the columns (metadata-only file). You use the Raw File destination to generate the metadata-only file without having to run the package. For more information, see Raw File Destination.
The raw file format contains sort information. The Raw File Destination saves all the sort information including the comparison flags for string columns. The Raw File source reads and honors the sort information. You do have the option of configuring the Raw File Source to ignore the sort flags in the file, using the Advanced Editor. For more information about comparison flags, see Comparing String Data.
You configure the Raw File by specifying the name of the name of the file that the Raw File source reads.
