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).

Calling Method

For details, see Calling APIs.

URI

PUT /v2/kafka/{project_id}/instances/{instance_id}/groups/{group}/reset-message-offset

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

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

Resetting 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 offset.

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

Either message_offset or timestamp must be specified.

timestamp

No

Long

Specified time that the offset is to be reset to. The value is a Unix timestamp, in millisecond.

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

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

Either message_offset or timestamp must be specified.

Response Parameters

None
