stephenmw opened a new issue, #24997:
URL: https://github.com/apache/beam/issues/24997

   ### What happened?
   
   BigqueryIO creates temporary datasets and tables and then later deletes 
them. Sometimes, the delete succeeds but the work-item commit fails. This means 
the temporary dataset/table is deleted but the work-item in which the delete 
happens is retried. Since BigqueryIO considers a 404 to be an error, the 
work-item is forever stuck when using a streaming job.
   
   This slows down draining of a job.
   
   To be resistant to failure, a 404 for a delete request should be treated as 
a success.
