Timo Walther created FLINK-20522: ------------------------------------ Summary: Make implementing a built-in function straightforward Key: FLINK-20522 URL: https://issues.apache.org/jira/browse/FLINK-20522 Project: Flink Issue Type: Sub-task Components: Table SQL / API, Table SQL / Planner Reporter: Timo Walther Assignee: Timo Walther
FLIP-65 has introduced new abstractions for functions. They make implementing user-defined functions straightforward. However, currently, these abstraction are not available for built-in functions. Adding a built-in function requires many changes at different locations as shown in FLINK-6810. This is error-prone, limits contributions, and is also not well supported by the current module system. -- This message was sent by Atlassian Jira (v8.3.4#803005)
