Kezhu Wang commented on ZOOKEEPER-4690:
---------------------------------------
Personally, I think both {{Stat}} and {{EphemeralType}} are exposed for client
usage. It is enough to retrieve ttl info from these two.
> Expose TTL ZNode information
> ----------------------------
>
> Key: ZOOKEEPER-4690
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4690
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.7.1
> Reporter: Ryan Ruel
> Priority: Minor
>
> When a ZNode is created with a TTL, there is currently no way to later read
> the ZNode and determine:
> 1. Is the ZNode configured with a TTL?
> 2. When will the TTL expire?
> This information could be useful, for example, where applications need to
> resurrect TTL-based tombstones into persistent ZNodes. Additionally, it would
> be useful for debugging via the CLI utility.
> I would expect this information to be available via the Stat object.
