In the pool definition, use "Catalog files=No". I guess it's a good 
idea to use a separate pool for this type of jobs :-)

A bit more difficult... the simple solution is to simply drop the 
index from the database.

Alternatively, you could use a run before job script to drop the 
index, and a run after job script to re-create it (I never tried 
this). Often, creating an index newly is much faster than adding the 
data for it one by one, as table entries arrive...
