Struct ReplicaFetchFacts 

pub struct ReplicaFetchFacts {
    pub request_leader_epoch: i32,
    pub current_leader_epoch: i32,
    pub target_matches: bool,
    pub reported_target_matches: bool,
    pub error_code: i16,
    pub diverging_epoch: i32,
}

What a follower knows about one row of a Fetch response when it decides what that row may change.

The row’s topic and partition identity is not among them: the host looks the row up by that identity (ResponseIndex::locate in the broker’s replicator) and never hands the kernel a row it could not attribute to exactly one followed partition.

Fields

request_leader_epoch: i32

The leader epoch this follower sent for the partition in the request that the row answers.

current_leader_epoch: i32

The leader epoch of the partition’s current replication target.

target_matches: bool

The replication target is the one the request was sent to.

reported_target_matches: bool

The row’s current_leader is either absent or exactly the current target’s leader and epoch.

error_code: i16

The row’s Kafka error code; 0 is NONE.

diverging_epoch: i32

The row’s KIP-320 DivergingEpoch.Epoch; -1, the schema default, means the row carries no divergence. Kafka’s FetchResponse.isDivergingEpoch tests the epoch, not the end offset.
