How about we keep the original getPurgeInterval() API but add documentation to
indicate it's in milliseconds?

Hmm, I don't think people want this.

> Support more fine tunable purgeInterval
> ---------------------------------------
>
> Key: ZOOKEEPER-4927
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4927
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.9.3
> Reporter: Li Wang
> Priority: Major
>
> A zookeeper instance went down in prod because it ran out of disk space. It
> turned out that the purge task was not able to keep up with the rate of
> snapshot taken. A new snapshot was taken every a couple of mins.
> Too snapshots were generate during autoPurge.purgeInterval. Since the unit is
> hour, so the min internal is 1 hour.
> To support writes heavy use case, we would need to support more fine tuned
> purge interval. For example, in minutes.
