Control execution of tLogrow based on context variable

Anonymous — Wed, 22 May 2013 17:37:48 GMT

Is there a way to control the execution of tLogrow based on context variables. I have a few tLogrow's in my job to print some input data to diagnose the cause of errors if any. However, including the tLogrow in the code generates a lot of output.
I want to execute the tLogrow for development environment but I want to disable it for test and production environments without changing the codes.
Is there a way I can setup the tLogrow based on the context variable so that I can specify the context variable value using the command line in dev, test and prod environments and control if the tLogrow output is generated or not.

The only way is to include a tFilterRow before the tLogRow that has a condition based on a context variable. If your tLogRow is in the middle of your flow, then you will have to redesign it slightly to have a tReplicate where the tLogRow now is with a second branch (the first being your normal flow) just to the tFilterRow and tLogRow.
I've actually thought for a while that conditional execution of components based on context variables would be a very useful feature. You can vote for my Jira TDI-13557 .
