title: Bigquery: how to stream streaming logs?
body: <p>Are there any best practises to log streaming logs into Bigquery? So that:
  (1), it wouldn't slow down data streaming itself
  (2), automatic alert can be sent when exceptional frequent errors happen or when certain errors happen
  (3), easy to get error/requests ratio stat. 
  Or, I can accomplish the above goals w/o bigquery? ( we are doing 24*7 continuous streaming so that the logs are supposed to continuously grow w/o up limit)</p>
