Talend : tJoin vs tMap
- tJoin Accept only 2 inputs ,1 main flow + 1 lookup
- tJoin joins two tables by doing an exact match on several columns. It compares columns from the main flow with reference columns from the lookup flow and outputs the main flow data and/or the rejected data.
- Accept multiple inputs ( can join multi tables on multiples keys )
- tMap is an advanced component, which integrates itself as plugin to Talend Studio.
