Does tMap and tReplicate in talend spark process all previous operations for each of its output flows?

Hi,

Can anyone clarify on whether tMap and tReplicate components in talend spark process all of its previous operations for each of its flows? We know the transformations are invoked at the time of action in spark, but does it happen multiple times for each output flow of tMap?

For e.g. Consider a flow as:

tFileInputDelimited->tSort->tMap->tFileOutputDelimited_1

->tFileOutputDelimited_2

Is tSort going to process the data differently for each output file?

If so, can tFilterRow(if applicable) be an option here?

Thanks in advance.
