Subj:   Requirements for Informatica full pushdown optimization
 
From:   Anomy Anom

Hello,

The PowerCenter full pushdown optimization requieres the source and target "database" to be the same. As I'm new to PowerCenter I'm not 100% sure what that means. Does it mean the database connection has to be the same?

In Teradata I would like to use a PowerCenter ELT-approach in the following way:

1) Initial load to Teradata landing-area via FastLoad - using database TRANSIT

2) Perform transformations in database STAGING

3) Load transformed transactions to database EDW


Questions:

1) Can mappings with source in TRANSIT and target in STAGING be full pushdown?

2) If not, would it help to create a view in STAGING on tables in TRANSIT and use that for the source?


Thanks in advance
