Both can co-exist if community accept both, so I am not particularly worried about it.

Thanks for the heads up though [~nixon]! > Backup and recovery support > --------------------------- > > Key: ZOOKEEPER-3419 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3419 > Project: ZooKeeper > Issue Type: New Feature > Components: server > Affects Versions: 3.6.0 > Reporter: Michael Han > Assignee: Michael Han > Priority: Major > Labels: Twitter > > Historically ZooKeeper has no intrinsic support for backup and restore. The > usual approach of doing backup and restore is through customized scripts to > copy data around, or through some 3rd party tools (exhibitor, etc), which > introduces operation burden. > This Jira will introduce another option: a direct support of backup and > restore from ZooKeeper itself. It's completely built into ZooKeeper, support > point in time recovery of an entire tree rooted after an oops event, support > recovery partial tree for test/dev purpose, and can help replay history for > bug investigation. It will try to provide a generic interface so the backups > can be directed to different data storage systems (S3, Kafka, HDFS, etc). > This same system has been in production at Twitter for X years and proved to > be quite helpful for various use cases mentioned earlier. This will be a > relative big patch, we'll try break the feature down and incrementally submit > the patches when they are ready. -- This message was sent by Atlassian Jira (v8.3.4#803005)
