[jira] [Closed] (FLINK-15804) Support the new type inference in Scala Table API scalar functions

["Timo Walther (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-15804?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Timo Walther closed FLINK-15804.
--------------------------------
    Fix Version/s: 1.14.0
     Release Note: Scalar functions that are called using Scala implicit conversions have been updated to use the new type system and new type inference. Users are requested to update their UDFs or use the deprecated `TableEnvironment.registerFunction` to restore the old behavior temporarily.
       Resolution: Fixed

I forgot to close this issue. Actually, we should have done aggregate functions and table functions as well in 1.14. But this will be postponed due to the large amount of failing tests.

> Currently, we cannot distinguish between old and new type inference for Scala Table API because those functions are not registered in a catalog but are used "inline". We should support them as well.
