tMap Inner Join Reject in Talend

We all know tMap is used to join the rows. Did you notice the "Catch lookup inner join reject" option in talend tMap component.

Today I'm going to explain its usage.

SAMPLE JOB:

In above picture LogRow1 with get join mating rows and LogRow2 will get Reject rows (the rows those are not match the inner join condition in tMap)

​Notice that in above image, row2 Join Model is "Inner Join" and reject output row "Catch lookup inner join reject" option has set to TRUE.
