Performance wise which is better joiner or look up ?
Give me with example?
Answer / abhinaw prakash
There is no definite answer to this.But if we are using
homogenous data sources its better to use Look up rather
than joiner.
Again Look up can only perform left outer join.So for other
Join we have to use Joiner.
