Jeff Zhang created FLINK-11970: ---------------------------------- Summary: 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 Reporter: Jeff Zhang
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 (v7.6.3#76005)
