Redefinição do deslocamento do grupo de consumidores para a posição especificada

Função

As instâncias do Kafka não oferecem suporte à redefinição on-line do deslocamento do consumidor. Antes de redefinir, pare o cliente para o qual o deslocamento deve ser reiniciado. Depois que um cliente é interrompido, o servidor considera o cliente off-line somente após o período especificado em ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG (1000 ms por padrão).
