What is a diff between joiner and lookup transformation

Answer Posted / mythili

Hi everybody,
Joiner is active transformation whereas lookup is passive
transformation.
Joiner returns only matching records whereas lookup
returns null if there is no match.
In join condition we can give only '=' operator but in
lookup condition !=,>=,<= are all possible.
Joiner will do left outer,right outer,normal,full outer
type of joins whereas lookup will do only left outer join.
