h1. Recipes
Curator implements all of the recipes listed on the ZooKeeper recipes doc (except two phase commit). Click on the recipe name below for detailed documentation.
+NOTE: Most Curator recipes will auto-create parent nodes of paths given to the recipe as CreateMode.CONTAINER. Also, see [[Tech Note 7|https://cwiki.apache.org/confluence/display/CURATOR/TN7]]
+regarding "Curator Recipes Own Their ZNode/Paths".
||Elections||
|[[Leader Latch|leader-latch.html]] \- In distributed computing, leader election is the process of designating a single process as the organizer of some task distributed among several computers (nodes). Before the task is begun, all network nodes are unaware which node will serve as the "leader," or coordinator, of the task. After a leader election algorithm has been run, however, each node throughout the network recognizes a particular, unique node as the task leader.|

Due to limitations in ZooKeeper's transport layer, a single queue will break if it has more than 10K\-ish items in it. This class

-
-A Utility to delete parent paths of locks, etc. Periodically checks paths added to the reaper. If at check time, there are no
-children, the path is deleted. Clients should create one Reaper instance per application. Add lock paths to the reaper as
-needed and the reaper will periodically delete them. Curator's lock recipes will correctly handle parents getting deleted.

-Utility to reap the empty child nodes in a parent node. Periodically calls getChildren() on the node and adds empty nodes to an internally managed Reaper.

-Utility to ensure that a particular path is created.
