Answer / sbvp

i agree with mr.satish we will use n number source in
single mapping

Answer / amedela chandra sekhar

WE CAN USE ANY NO OF SOURCES IN A MAPPING AT A TIME.THERE IS NO LIMIT.

Answer / akash

When we are using multiple sources and bringing them in a
single data flow, we need joiners.

No. of Joiners = No. of sources - 1

So this will also depend upon how many joiners can we use
in our mapping.

As per my understanding we can use upto 8 joiners in a
mapping so that it remains stable due to cache memory
constraint.

Please let me know if this is correct.
