Flavio Junqueira commented on ZOOKEEPER-1925:
---------------------------------------------
I suppose you're referring to expiration of a znode without associating it to a
session like we do with ephemerals, yes? If the use is garbage collection,
could you write an app-level thread that periodically scans the tree (or a
sub-tree) for old znodes.

> Today whenever a znode is created; it stays there for ever. We all know that
> there is a limitation in terms of how many nodes a system can handle. It
> would be nice to have a way to specify expiry time for every znode thereby
> stale zondes are cleandup automatically after sufficiently large time. any
> thoughts?
