Field	Description
replica_id	The broker ID of the follower, of -1 if this request is from a consumer.
max_wait_ms	The maximum time in milliseconds to wait for the response.
min_bytes	The minimum bytes to accumulate in the response.
max_bytes	The maximum bytes to fetch. See KIP-74 for cases where this limit may not be honored.
isolation_level	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.
topics	The topics to fetch.
topic	The name of the topic to fetch.
partitions	The partitions to fetch.
partition	The partition index.
fetch_offset	The message offset.
partition_max_bytes	The maximum bytes to fetch from this partition. See KIP-74 for cases where this limit may not be honored.

Field

Description

max_wait_ms

The maximum time in milliseconds to wait for the response.

min_bytes

The minimum bytes to accumulate in the response.

max_bytes

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

isolation_level

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.

Field	Description
throttle_time_ms	The duration in milliseconds for which the request was throttled due to a quota violation, or zero if the request did not violate any quota.
groups	Each described group.
error_code	The describe error, or 0 if there was no error.
error_message	The top-level error message, or null if there was no error.
group_id	The group ID string.
group_state	The group state string, or the empty string.
group_epoch	The group epoch.
assignment_epoch	The assignment epoch.
topology	The topology metadata currently initialized for the streams application. Can be null in case of a describe error.

name	The name of the topic.
partitions	The number of partitions in the topic. Can be 0 if no specific number of partitions is enforced. Always 0 for changelog topics.
replication_factor	The replication factor of the topic. Can be 0 if the default replication factor should be used.
topic_configs	Topic-level configurations as key-value pairs.

port	port of the endpoint
client_tags	Used for rack-aware assignment algorithm.
task_offsets	Cumulative changelog offsets for tasks.
subtopology_id	The subtopology identifier.
partition	The partition.
offset	The offset.
task_end_offsets	Cumulative changelog end offsets for tasks.
assignment	The current assignment.
