ASF GitHub Bot commented on FLINK-10887: ---------------------------------------- jgrier commented on issue #7099: [FLINK-10887] [jobmaster] Add source watermark tracking to the JobMaster URL: https://github.com/apache/flink/pull/7099#issuecomment-445316366 > Can we always assume that the user-jar/class loader will be available where the `AggregateFunction` is needed? If yes, I think this is a nice approach! (We can probably use concrete types in the interface, though) @aljoscha I'm actually not sure if the user code classloader is available from the JobMaster but I would think that's reasonable since there's a 1:1 relationship between the JobMaster and a single job. WRT concrete types in the RPC interface I'm not sure what you're thinking there. The concrete types are not known in this approach. The types are up to the user/client and can be different for each named aggregate. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
