BigQuery Patch Operation in Dataflow Java SDK
<p>Per the <a href="https://stackoverflow.com/questions/30687501/how-do-i-write-to-bigquery-a-schema-computed-during-execution-of-the-same-datafl">question</a> re: making a custom Sink to update Schemas dynamically in Dataflow, I was wondering if the <code>Patch</code> operation is exposed in BigQueryIO API somewhere? </p>

<p>This is a crucial piece of updating schemas on the fly. We are merging schemas as they come in in backwards compatible ways. </p>
