      Description

      Since Kafka require all the reading happen in the leader for the consistency.

      in case, for large volume data of a Topic have a number of consumers, among them, some consumers are Not latency-sensitive But Data-Loss sensitive have a consuming lag, then, it will pollute the Page cache as they are reading from the disk, hence, for other consumers which are latency-sensitive will be sad due to the pagecache miss

      If there could be possible for the reading can happen in replicas for a eventually consistent (likely version based), thus, consumers marked as "read from replica" can be separated from others
