Question
Instead of creating a file, the Sink adapter can be used for temporary output. The advantages of the using the Sink adapter are:
Options
- Afaster map performance.
- Breduced memory usage.
- Creduced disk space usage.
- Dreduced number of output cards
- Ereduced file resource conflicts when running multiple instances of the map..
Why each option
No correct answer was provided for this question. Based on IBM Sterling map engine behavior, the Sink adapter discards output data without writing to disk, eliminating file I/O overhead and file handle usage.
Faster map performance is a valid benefit because eliminating file write I/O reduces overall execution time, so this choice is not clearly wrong in IBM Sterling documentation.
The Sink adapter does not reduce memory usage - data is still processed in memory before being discarded, so memory consumption is not reduced.
Reduced disk space usage is a direct benefit because no output file is created, so this choice is not wrong.
The number of output cards is a design-time artifact and is not reduced by using the Sink adapter in place of a file adapter.
Reduced file resource conflicts is a valid benefit because no file handle is opened or locked, so this choice is not wrong.
