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.
The transformation reads the value in bytes. The default value is 400,000 bytes. The maximum value is 2,147,483,647 bytes. You can use a parameter to specify the cache file size.
