what is the difference between look up and joiner(don't say
joiner sopport only = where as look up support non-equijoin).
Answer Posted / kondeti srinivas
with lookup we can do left join only
but with joiner we can do all the joins(normal,master
outer,detail outer,full outer)
for mutiple matching only it will give one return value
based on lookup policy(first value or last value like that)
in lookup transformation. but in the joiner transformation
it will give the output for all the matchings
if any one knows more than this please let me know
