According to the Kafka 8 documentation under broker configuration. There are these parameters and their definitions.
log.retention.bytes -1 The maximum size of the log before deleting it log.retention.bytes.per.topic "" The maximum size of the log for some specific topic before deleting it I'm curious what the first value 'log.retention.bytes' is for if the second one is for per topic logs, because aren't all logs generated per topic? Is this an aggregate value across topics? Related question, is there a parameter for kafka where you can say only hold this much TOTAL data across all topic ( logs/index together )? I.e. our hosts have this much available space and so value log.retention.whatever.aggregate == 75% total disk space.
