Jason Gustafson updated KAFKA-12505: ------------------------------------ Labels: kip-500 (was: ) > Should kafka-storage.sh accept a non-UUID for its --cluster-id parameter? > ------------------------------------------------------------------------- > > Key: KAFKA-12505 > URL: https://issues.apache.org/jira/browse/KAFKA-12505 > Project: Kafka > Issue Type: New Feature > Reporter: Ron Dagostino > Priority: Minor > Labels: kip-500 > > Should StorageTool support accepting non-UUIDs via its --cluster-id argument? > One purpose of the tool is to minimize the chance that a broker could use > data from the wrong volume (i.e. data from another cluster). Generating a > random UUID via the --random-uuid parameter encourages using a globally > unique value for every cluster and is consistent with the behavior today with > ZooKeeper, whereas allowing a non-UUID here would increase the chance that > someone could reuse a Cluster ID value across clusters and short-circuit the > risk mitigation that this tool provides. > Discuss... -- This message was sent by Atlassian Jira (v8.3.4#803005)
