Hi team,

I am using expression evaluator i want to read one parameter from data collector configuration file.

Parameter is  = runtime.conf_expression=${record:value('/salary')}

While reading in expression evaluator I am reading in this way ${runtime:conf('expression')} but output is coming as string . I want output as expression so that it can be evaluated.

StreamSets pipelines do not allow treating runtime parameters as expressions because that tends to create security issues with untrusted code. Instead, you should create a set of options and pass in the key for the one you want.

If the number of options is large, this may be easier to do using a switch-case statement in a JavaScript (or other scripting) processor.
