queries in parallel

Hello,

what components should I use if I want to perform parallel queries to 3 different oracle databases and only when all of them are finished would I like to run the tDBRow component. I don't know how to run these queries in parallel.

Thank you.

Hello,

In Talend Studio, parallelization of data flows means to partition an input data flow of a subJob into parallel processes and to simultaneously execute them, so as to gain better performance. These processes are executed always in a same machine.

For your use case, you could use parallelization feature in talend with tOracleInput component.

Feel free to let us know if this documentation helps.

Best regards

Sabrina
