KIP-1023 — Follower fetch from tiered offset

Accepted Kafka 4.2 Tiered StorageBroker

Enables follower replicas to start fetching from the tiered storage offset (the remote log start offset) rather than always from local log start, when rebuilding auxiliary state (leader epoch cache, producer snapshots) from the leader. Without this, followers on tiered-storage-enabled topics redundantly fetch local segments that overlap with remote storage, slowing restoration.
