Hi Ram, You are right, the effect of DefaultRollingPolicy not always rolling on checkpoint leads to unusable non-latest savepoints.
My question is, should DefaultRollingPolicy be changed so that it always roll on checkpoint to provide a better user experience? I'd imagine most StreamingFileSink user starts off with DefaultRollingPolicy. Users finding that they cannot restore from earlier savepoint when they intend to replay events and consequently is a suboptimal experience. Of course, changing default behaviour may have huge impact, this is also why I'd like to understand: what's the motivation behind making DefaultRollingPolicy not always roll on checkpoint? It's worth considering the trade-offs as current default behaviour make non-latest savepoints unrestorable . Thank you Keith
