I think during compile time it would be hard to detect, as this is somewhat a dependency management issue - unless we shade the aws sdk and only allow to pass these shaded objects as an input? Otherwise, do we think an error during sink startup makes sense that the sdk classes used are incompatible with the one used in the sink due to serialization issues? similar to how flink fails if an object that is passed to the operators is not serializable -- This is an automated message from the Apache Git Service.
