I am analyzing existing Job in Datastage.Could anybody please clarify below doubt with respect to Join stage?

I have 4 Tables.These four tables are input to Join stage.Join type=Left outer.In link ordering tab following details are mentioned.

Table1-Left

Table2-Intermediate1

Table3-Intermediate2

Table4-right

I know how left outer join works if it is two inputs to join stage and in this case i am unable to understand how join operation will be performed?

In this case all records from the left will move to output link with matching records from Intermediate1 ,Intermediate2 and right link.

Multi-input left outer join works the same way it does in a query engine. Essentially pairwise, left to right.
