title: Big Query Public Dataset Events/Triggers?
body: <p>Is there a way to get a notification whenever new rows are inserted into public dataset? Do BQ datasets/tables support triggers or events for us to use when the data changes?</p>
  
  <p>I am experimenting with public datasets and wish to execute my recomputation logic whenever Google updates a public dataset.
  I wish to invoke a CloudFunction to compute something whenever new rows are inserted into noaa_gsod.gsod_2018 public dataset.
  Now, it doesn't have to be a fancy serverless target - I am happy to subscribe to a topic on PubSub and use a GCE VM instance to execute my logic, if BQ public dataset can somehow publish such messages to PubSub.
  Unfortunately I couldn't find a way to get notified of changes/updates to public dataset.
  Would love to hear from the community if anyone has experimented on this matter.
  Thanks,
  Dheerendra Nath.</p>
