How to avoid multiple tmap lookups in talend bigdata

Hi Team,

 

i have input file having different id columns . For all the id's, i have to get corresponding description. But the lookup file same. When i am using single tmap with multiple lookups , it is not allowing and saying that need to use similar expression. Please help me on this.

 

When i am doing multiple lookup's with multiple tmap it is working. I have to avoid multiple tmaps for the same lookup file having different soruce id's.

 

 

Regards

Prasanna

@gpr ,you can use tHasoutput and tHasInput combination components to do this in standard bigdata jobs.

tCacheIn and tCacheOut can be used in the Spark Batch and Spark Streaming Job framework.
