npawar opened a new issue #7280:
URL: https://github.com/apache/pinot/issues/7280


   Sometimes, reset API is called on a consuming segment, to make the 
consumption restart. This is quite desirable in case of schema evolution, where 
someone added a new column, and want to force the consuming segment to restart, 
so that the new values are seen in the consuming segment. While consumption can 
be restarted even by restarting the server that contains that segment, that is 
often more expensive (multiple tables, multiple consumers on that server) and 
hence folks don't like that option.
   Calling a reset will take the segment to OFFLINE and back to ONLINE. If 
there are multiple replicas, all of them will get reset at once. This will 
cause downtime, even though we have replication. There is no way to make the 
reset happen once replica at a time.
   A noDowntime option would be nice.
