Hi Support Team,
I have few questions related to graphLookup. I am not clear about the different use of startWith and connectFromField. In all the available lectures on this topic, the field used for both these parameters was the same. Then what is the use of having two different parameters in the syntax. And if both these parameters are different and are used differently, then please provide an example. Also I would encourage you to please have this incorporated into the lecture too since the lecture does not bring out the difference properly
Additionally startWith had the ‘$’ sign which was further confusing. We did not ‘$’ sign with either the connectFrom or connectToField but we did it use it for startWith why?
One more thing I know that when we use ‘$’ sign it refers to field path. But what is field path and why we some times use the ‘$’ sign but sometimes we don’t like for eg even in match stages we don’t use ‘$’ sign along with field name but in few cases in project I saw the use of ‘$’ sign. When exactly is the ‘$’ sign used and when is it not used.
