---------------------------------
Summary: Clarify differences of overloaded term "user-defined
function"
Key: FLINK-23199
URL: https://issues.apache.org/jira/browse/FLINK-23199
Project: Flink
Issue Type: Improvement
Components: API / DataStream, Documentation, Table SQL / API
Reporter: Ingo Bürk
The term "user-defined function" exists both in DataStream API[1] and Table /
SQL API[2], but has different meanings in each. For users this can be confusing
when looking at the different possible interfaces[3], so we should improve the
documentation to make it clear that these are two different concepts.
