Abstract
Reporting time progress for written events on a stream is disclosed. The system comprises operations for obtaining time report information comprising respective timestamp information and respective positional offset information for respective writers with respect to events written to a stream by the respective writers. The operations further comprise aggregating the time report information and determining a lowerbound, e.g., a minimum timestamp before which new events to be written by the stream storage system will no longer arrive, and determining an upperbound, e.g., a stream offset representative of an overall offset of the events written thus far in the stream. The operations further comprise storing the minimum timestamp and the stream offset in a data structure for the events written thus far.
