--------------------------------------
Summary: Annotate SourceFunction and SinkFunction as deprecated
Key: FLINK-25852
URL: https://issues.apache.org/jira/browse/FLINK-25852
Project: Flink
Issue Type: Technical Debt
Components: Connectors / Common
Reporter: Martijn Visser
The SourceFunction and SinkFunction should not be used by connectors anymore,
who should be using the new Source API [(See
FLIP-27|https://cwiki.apache.org/confluence/display/FLINK/FLIP-27%3A+Refactor+Source+Interface]
+ [Sources
documentation)|https://nightlies.apache.org/flink/flink-docs-master/docs/dev/datastream/sources/]
and/or Sink API [(See
FLIP-143|https://cwiki.apache.org/confluence/display/FLINK/FLIP-143%3A+Unified+Sink+API]
or
[FLIP-171)|https://cwiki.apache.org/confluence/display/FLINK/FLIP-171%3A+Async+Sink].
Therefore we should properly annotate these as deprecated so they can be
removed in future versions.
