Kafka consumer group offset retention

Question

How long does kafka store the offset of a consumer-group after all consumers in that group fail? Is there a configuration variable for this?

Answer 1

The right property name is:

offsets.retention.minutes

from https://kafka.apache.org/documentation/#brokerconfigs

Answer 2

The value can be configured in kafka broker using:

offsets.retention.minutes

The default is 24 hours.

See: the Kafka broker config docs.

Answer 3

I have added following property in Kafka configuration, it changed the offset retention time to 7 days, and working good.

offsets.retention.minutes=10080
