title: Is StreamTableEnvironment able to run against batch stream?
body: <p>I am reading at <a href="https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/table/data_stream_api/" rel="nofollow noreferrer">https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/table/data_stream_api/</a></p>
  <p>It says:</p>
  <blockquote>
  <p>Currently, the StreamTableEnvironment does not support enabling the
  batch execution mode yet. Nevertheless, bounded streams can be
  processed there using the streaming execution mode but with lower
  efficiency.</p>
  </blockquote>
  <p>Does it mean that StreamTableEnvironment can work with batch stream but with lower effiency since the StreamTableEnvironment can't be configured to run in batch mode?</p>
