Fields

cluster_id: Option<String>

The clusterId if known. This is used to validate metadata fetches prior to broker registration.

replica_id: i32

The broker ID of the follower, of -1 if this request is from a consumer.

replica_state: ReplicaState

max_wait_ms: i32

The maximum time in milliseconds to wait for the response.

min_bytes: i32

The minimum bytes to accumulate in the response.

max_bytes: i32

The maximum bytes to fetch. See KIP-74 for cases where this limit may not be honored.

isolation_level: i8

This setting controls the visibility of transactional records. Using READ_UNCOMMITTED (isolation_level = 0) makes all records visible. With READ_COMMITTED (isolation_level = 1), non-transactional and COMMITTED transactional records are visible. To be more concrete, READ_COMMITTED returns all data from offsets smaller than the current LSO (last stable offset), and enables the inclusion of the list of aborted transactions in the result, which allows consumers to discard ABORTED transactional records

session_id: i32

The fetch session ID.

session_epoch: i32

The fetch session epoch, which is used for ordering requests in a session.

topics: Vec<FetchTopic>

The topics to fetch.

forgotten_topics_data: Vec<ForgottenTopic>

In an incremental fetch request, the partitions to remove.

rack_id: String

Rack ID of the consumer making this request.

unknown_tagged_fields: Vec<RawTaggedField>

Unknown tagged fields.
