title: BigQuery load compressed data from Cloud Storage
body: <p>I have a lot of *.gz files in my Google Cloud Storage.
  I want to load those data to BigQuery.
  I've tried to execute </p>
  
  <pre><code>bq load --source_format=AVRO projectId:dataset.table gs://bucket/*.gz
  </code></pre>
  
  <p>But received error</p>
  
  <pre><code>The Apache Avro library failed to parse file gs://bucket/f92d8ae3-6eba-4e35-9fc0-b8f31b4b9881-part-r-00004.gz.
  </code></pre>
  
  <p>Is it possible to upload compressed data to BigQuery? What is the best pracrise for those problems?</p>
