Read same Persistent DataSet multiple times in a job
Posted: Fri Nov 24, 2006 9:14 am
Folks,
I'm creating a job that needs to look into a list of values using multiple fields in the incoming file. In server it is quite common practice to set up a list in a hashed file and have multiple links from the single hashed file to the transformer performing the lookup.
The EE version doesn't like that so much. What I've done is created multiple Dataset stages, all pointing to the same underlying persistent dataset and linked each one separately to the lookup stage.
Thus far I have been quite successful with this approach, encountering no errors.
I have not been able to find anything in the manuals or on these forums that explicitly states that this is or is not a permissible thing to do with persistent datasets.
Does anyone out there have any experience using datasets this way?
Thanks in advance for your responses,
Rob W
