Certain flow snaps like “Filter”, “Head”, “Tail” when used in a complex pipeline doesn’t generate a preview while validating the entire pipeline however these generate a preview if the pipeline is simple.
For instance, if I’m trying to read data from an excel file with 100k+ records and use either ‘filter’ or ‘head/tail’, I can see the preview when the pipeline has been validated but it doesn’t generate one when the pipeline is huge. Any specific reason behind this?
I would want to see the preview as the pipeline that I’m currently developing is a complex one (multiple snaps prior to “flow” snaps), thereafter it needs a ‘filter + head/tail’ (i.e. flow snaps) and then it will again require a bunch of other snaps after those ‘filter + head/tail’ making it complex again.
Help on this matter would be highly appreciated.
