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).
