Specifies the directory to which the Data Integration Service writes temporary data for the current transformation. The Data Integration Service writes temporary files to the directory when the volume of input data is greater than the available system memory. The Data Integration Service deletes the temporary files after the mapping runs.

You can enter a directory path on the property, or you can use a parameter to identify the directory. Specify a local path on the Data Integration Service machine. The Data Integration Service must be able to write to the directory. The default value is the CacheDir system parameter.

Determines the amount of system memory that the Data Integration Service uses to sort the input data on the transformation. The default value is 400,000 bytes. You can use a parameter to specify the cache file size.

Before it sorts the data, the Data Integration Service allocates the amount of memory that you specify. If the sort operation generates a greater amount of data, the Data Integration Service writes the excess data to the cache file directory. If the sort operation requires more memory than the system memory and the file storage can provide, the mapping fails.

Amount of detail that appears in the log for this transformation. You can choose terse, normal, verbose initialization, or verbose data. Default is normal.
