damccorm opened a new issue, #20440: URL: https://github.com/apache/beam/issues/20440
Observed on v2.22.0 When withMaxReadTime() is used, Beam creates an BoundedReadFromUnboundedSource [1]. The ReadFn<T\> class in BoundedReadFromUnboundedSource which is responsible for reading records from source. You can see this class doesnt verify if there is a recoverable checkpoint exist. Instead it always creates Reader with checkpointMark set as null [2].
