Input to lookup stage
Posted: Thu May 26, 2005 5:42 am
Just wanted to know....what can be input (looked up) by a lookup stage. It can obviously be a file/table; but when I added a lookup to a file and then looked up to another (see below code) no records matched in Lkp2.
It is obvious that by the time Lkp2 tried the lookup no records were ready from Lkp1.
Q1> Does Lookup stage output only after all recs are processed?
Q2> From what stages can a lookup stage lookup? (In one case I have an aggregator o/p being looked up and it works)

Code: Select all
file1->Lkp2

RefFile2->Lkp1
