from Source 100 rows are coming, on target there are 5 m
rows which options is better to match data
1. Joiner
2 No cache
3. Static
4. Dynamic
Answer Posted / arnab
Lookup with No cache will make it faster , personal opinion
though , there are other ways do it also , if you have a
common key between the source and the target and they are
on the same database , it would be easier and faster to do
a join in the source qualifier itself and let the database
handle the query rather than Informatica server
