Resetting Consumer Group Offset to the Specified Position

Function

Kafka instances do not support resetting the consumer offset online. Before resetting, stop the client for which the offset is to be reset. After a client is stopped, the server considers the client offline only after the time period specified in ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG (1000 ms by default).

NOTE:

This API is out-of-date and may not be maintained in the future. Use the API described in Resetting Consumer Group Offset to the Specified Position.

Call Method

For details, see How to Call an API.

URI

POST /v2/{project_id}/instances/{instance_id}/management/groups/{group}/reset-message-offset

Table 1 URI parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID. For details, see Obtaining a Project ID.

instance_id

Yes

String

Instance ID.

group

Yes

String

Consumer group name.

Request Parameters

Table 2 Request body parameters

Parameter

Mandatory

Type

Description

topic

No

String

Topic name.

partition

Yes

Integer

Partition number. The default value is -1, indicating that all partitions are reset.

message_offset

No

Long

This parameter resets consumer group offset to the specified position.

  • If this position is earlier than the current earliest offset, the offset will be reset to the earliest position.
  • If this position is later than the current latest offset, the offset will be reset to the latest position.

Either message_offset or timestamp must be specified.

timestamp

No

Long

This parameter resets consumer group offset to the specified time. The value is a UNIX timestamp, in millisecond.

  • If this timestamp is earlier than the current earliest timestamp, the offset will be reset to the earliest timestamp.
  • If this timestamp is later than the current latest timestamp, the offset will be reset to the latest timestamp.

Either message_offset or timestamp must be specified.

Response Parameters

None

Example Requests
