Subject [jira] [Updated] (FLINK-23199) Clarify differences of overloaded term "user-defined function"
Date Thu, 01 Jul 2021 06:03:00 GMT

     [ https://issues.apache.org/jira/browse/FLINK-23199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ingo Bürk updated FLINK-23199:
------------------------------
    Description: 
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.
