title: How to avoid inconsistency due to concurrent queries in Big Query
body: <p>Is there a way to ensure that multiple concurrent reads and writes in Big Query do not suffer from inconsistency?</p>
  
  <p>I don't think there is a 'transaction' mechanism for Big Query tables. Is it? How are such scenarios usually handled?</p>
  
  <p>I am using Java API for querying and writing data in the Big Query. </p>
  
  <p>Any pointers will help. Thanks.</p>
