Rank Transformation Advanced Properties

Rank Transformation Advanced Properties

Configure properties that help determine how the Data Integration Service processes data for the Rank transformation.
Configure the following properties on the
Advanced
 tab:
Top/Bottom
Specifies whether you want the top or bottom ranking for a column.
Number of Ranks
Number of rows to include in the top or bottom ranking.
Case-Sensitive String Comparison
Specifies whether the Data Integration Service uses case-sensitive string comparisons when it ranks strings. Clear this option to have the Data Integration Service ignore case for strings. By default, this option is selected.
Cache Directory
Directory where the Data Integration Service creates the index cache files and data cache files. Verify that the directory exists and contains enough disk space for the cache files.
Enter multiple directories separated by semicolons to increase performance during cache partitioning. Cache partitioning creates a separate cache for each partition that processes the transformation.
Default is the CacheDir system parameter. You can configure another system parameter or user-defined parameter for this property.
Rank Data Cache Size
Amount of memory that the Data Integration Service allocates to the data cache for the transformation at the start of the mapping run. Select Auto to have the Data Integration Service automatically calculate the memory requirements at run time. Enter a specific value in bytes when you tune the cache size. Default is Auto.
Rank Index Cache Size
Amount of memory that the Data Integration Service allocates to the index cache for the transformation at the start of the mapping run. Select Auto to have the Data Integration Service automatically calculate the memory requirements at run time. Enter a specific value in bytes when you tune the cache size. Default is Auto.
Tracing Level
Amount of detail that appears in the log for this transformation. You can choose terse, normal, verbose initialization, or verbose data. Default is normal.
