    Description

      As stated in the documentation this is how table functions should be used in Java Table API:

      // Register the function.
      tableEnv.registerFunction("split", new Split("#"));
      
      myTable.join("split(a) as (word, length)");
      

      However Table.join(String) was removed sometime ago and now it is impossible to use Table Functions in Java Table API.
