> As a user, I would like to be able to create a node that is NOT tied to a
> session but that WILL expire automatically if action is not taken by some
> client within a time window.
> I propose this to enable clients interacting with ZK via http or other "thin
> clients" to create ephemeral-like nodes.
> Some ideas for the design, up for discussion:
> The node should support all normal ZK node operations including ACLs,
> sequential key generation, etc, however, it should not support the ephemeral
> flag. The node will be created with a TTL that is updated via a refresh
> operation.
> The ZK quorum will watch this node similarly to the way that it watches for
> session liveness; if the node is not refreshed within the TTL, it will expire.
> QUESTIONS:
> 1) Should we let the refresh operation set the TTL to a different base value?
> 2) If so, should the setting of the TTL to a new base value cause a watch to
> fire?
> 3) Do we want to allow these nodes to have children or prevent this similar
> to ephemeral nodes?
