Jeff Zhang commented on FLINK-11970: ------------------------------------ ping [~tiwalter] > TableEnvironment#registerFunction should overwrite if the same name function > existed. > -------------------------------------------------------------------------------------- > > Key: FLINK-11970 > URL: https://issues.apache.org/jira/browse/FLINK-11970 > Project: Flink > Issue Type: Improvement > Components: Table SQL / API > Reporter: Jeff Zhang > Assignee: vinoyang > Priority: Major > > Currently, it would throw exception if I try to register user function > multiple times. Registering udf multiple times is very common usage in > notebook scenario. And I don't think it would cause issues for users. > e.g. If user happened to register the same udf multiple times (he intend to > register 2 different udf actually), then he would get exception at runtime > where he use the udf that is missing registration. -- This message was sent by Atlassian Jira (v8.3.4#803005)
