 2.0. If you are still using a connector that is built on
top of <code>SourceFunction</code> please migrate it to
<a href="https://github.com/apache/flink/blob/master/flink-core/src/main/java/org/apache/flink/api/connector/source/Source.java"><code>Source</code></a>.
<code>SinkFunction</code> is not officially deprecated, but it is also approaching end-of-life and will be superseded by
<code>SinkV2</code>.</li>
