Log Cleanup Policies

The video tutorial introduces the concept of log cleanup in Kafka, explaining how data expiration is managed through policies. The default policy for user topics is 'delete', which removes data based on age and size. Another policy, 'compact', is used for consumer offsets, deleting duplicate keys. Log cleanup helps manage disk space and system performance, occurring when partition segments are committed. The frequency of cleanup is balanced to optimize resource use.
