GitHub user BewareMyPower added a comment to the discussion: Messages lost with new topic and regex subscription
The same applies to a partitioned consumer. IMO, when a consumer found new topics/partitions, the subscription initial position **should be changed to earliest** no matter what the original initial position is. Usually consumers use latest initial position to discard outdated messages. However, assuming that partitions were dynamic increased, i.e. there're some producers and consumers serving this partitioned topic currently. If producers found the increased partitions before consumers, in consumer's view, those messages before it consumes **shouldn't be considered outdated**. What do you think of this change? @sijie GitHub link: https://github.com/apache/pulsar/discussions/18458#discussioncomment-4133562 ---- This is an automatically sent email for dev@pulsar.apache.org.
