title: It is possible to Stream data from beam (Scio) to an S3 bucket?
body: <p>Currently, I'm working on a project which extracts data from a BigQuery table using Scio in Scala.</p>
  <p>I'm able to extract and ingest the data into ElasticSearch, but I'm trying to do the same but using an S3 bucket as storage.</p>
  <p>Certainly, I'm able to write the data into a txt file using the method <code>saveAsTextFile</code>, and then upload it from my machine to the s3 bucket adding the correct libraries into sbt.</p>
  <p>However, I don't know if it is possible to write a <code>saveCustomOutput</code> code to write the data right away to S3, instead of using a local storage.</p>
