Review comment:
Hi Pablo. Thanks for the inputs. I thought the same. But I am confused
how the actual values come in? With the single field update whatever value
comes in from the pipeline will be set as the value for the field. Now if we
have to update for multiple fields how it can be done ? I am not pretty sure
how it works in beam. Hope my question is clear.
Upserts functionality can definitely be added.
