Options
| Option | Description |
|---|---|
Transform name | Name of the transform, this name has to be unique in a single pipeline. |
Sort directory | The directory in which the temporary files are stored in case when needed; the default is the standard temporary directory for the system |
TMP-file prefix | Choose an easily recognized prefix so you can identify the files when they show up in the temp directory. |
Sort size | The more rows you store in memory, the faster the sorting process because fewer temporary files must be used and less I/O is generated. |
Free memory threshold (in %) | If the sort algorithm finds that it has less available free memory than the indicated number, it will start to page data to disk. |
Compress TMP Files | Compresses temporary files when they are needed to complete the sort. |
Only pass unique rows? | Enable if you want to pass unique rows only to the output stream(s). |
Fields table | Specify the fields and direction (ascending/descending) to sort. You can specify whether to perform a case sensitive sort (optional) |
