tJava and tJavaRow

Anonymous — Sat, 16 Nov 2024 14:32:29 GMT

Hello,
In Pentaho Data integration (Kettle) I use the step "Java Script Value" to calculate new fields, alter existing ones or manipulate a row, and i would like to know the equivalent for that in Talend. Is it tJava component or tJavaRow components and what's the difference between these two components.
Also if someone has done a benchmarking (Talend against Kettle) that will be useful for me!
Thanks in advance!
Best Regards
hamma

Hi Hamma

yes, it's easy to edit the rows directly using the tJavaRow component of TOS.

what's the difference between these two components.

tJavaRow is only for the main part of the codes, so the codes will be executed in each row.
tJava is only for the "begin" part of the codes, so it will be executed before.
