I'm all for adding validation flows to the sdk. Just not sure about committing relatively large binaries from the quickstarts to the repo.

Use a markdown file with little words is enough, we can comment it ( the file type and size we support etc.) in the doc

which large binaries?

[sadath-12]

its just one main.go which would also help us to validate in our ci easily also I had the same thought which you commented . but if we have a look carefully there are many other examples directly taken from examples repo including pubsub (only few things are changed but overall its same) so I had to make a choice of consistency here

This needs to be added to the validation workflow to have any effect on CI.
I'll get a PR raised
