(2) Two new dynamic server configuration items: log.remote.copy.lag.ms and log.remote.copy.lag.bytes
If a user wants to enable the lazy copy behavior for all the topics (including the new ones), then they can set these broker-level dynamic configs. Otherwise,
it will be hard for the user to create the new topics with these configs set when remote storage is enabled.
