5 Tips For Better DataStage Design #7



#1. In case the partition type for the next immediate stage is to be changed then the ‘Propagate partition’ should be set to ‘Clear’ in the current stage.



#2. Make sure that appropriate partitioning and sorting are used in the stages, where ever possible. This enhances the performances. Make sure that you understand the partitioning being used. Otherwise leave it auto.

#3. For fixed width files, final delimiter should be set to 'none' in the file format property.

#4. If any processing stage requires a key ( like remove duplicate, merge, join, etc ) the Keys, sorting keys and Partitioning keys should be same and in the same order

#5. To improve Funnel, all the input links must be hash partitioned on the sort keys.
