Retention period for __consumer_offsets topic

Hi,

What should be the retention period for __consumer_offsets topic? Should it
be the same as other Kafka topics?

Thanks,
Nitin

Is that possible to make __consumer_offsets retention to be size-based
instead of time-based like with "retention.bytes" property?

Hi Nitin,

Default in Kafka 2.0+ is 7 days, previously it was 24 hours IIRC. Only
reason you need to change it is if you anticipate having a whole consumer
group offline for longer than your current retention period for
debugging/maintenance etc.

Cheers,
