Set Variable Node

The value assigned can be of type -

• Select - Selects a part of the output from the previous node. For instance previous node is request node that outputs { "id": 10, "category" : [ {"id" : 10, "status" : "available"} ], .....} , then you can use id or category.0.id to assign value to the variable. The actual values will be calculated on the fly when the graph is run.

• Number - Assigns a value of type number to the variable.

• Now - Assigns a value of type now() epoch timestamp to the variable. The value of now() is calculated on the fly during graph run.

• Expression - You can compute an expression on the fly to assign value to this variable. For instance , create a variable startTime that is assigned now() - 3minutes
