CDC Internal Functionality
Posted: Thu Jan 25, 2007 2:46 pm
Hi,
Can someone pls explain the internal algorithm or logic that Datastage CDC stage uses to compare the Before & After Dataset?
Does it take the 2 sets of data in memory (per partition) and do a one to one row comparision..or some other way.
Is there any architecture diagram or doc for this available anywhere?
