Variable Expressions node is time consuming

Hi All,

Variable Exressions node takes much longer to execute when compared to String Manipulation (Variable) node.
E.g:
image

Expression in both nodes: string(“Test”)

Time taken:
image

In a normal workflow without any loop this shouldn’t be a problem. But a time sensitive production workflow with loops around the node (our case), this is a big problem.

Is there any easy explanation for this time consumption? We are currently solved this issue by replacing Variable Expressions node with String Manipulation (Variable) node. If we know the reason(s) begind this, this will help us to design our workflow more efficiently.

Thanks in advance :slight_smile:

Hello @nithinth7,

would say same reason as here:

Is there any reason (function) why you are using Variable Expressions and not String Manipulation (Variable) node?

Hi Ivan,

Thanks for the reply.
No particular reason. Developer simply used the first node came to mind. And column expression is really powerful and multipurpose in comparison.

Hello Nithin,

I see. Then I would simply use String Manipulation and/or Rule Engine Variable nodes.
