Github user davidyan74 commented on the issue: https://github.com/apache/incubator-samoa/pull/55 @bhupeshchawda For the slow execution, we can do some tuning on the timeout window count, the window width and the number of tuples being generated for each window. For the serialization, is it possible to use java serializer for the affected fields by using @FieldSerializer.Bind(JavaSerializer.class) within the Apex operator without changing Samoa code?
