Our set up is following.

- Controller (leader elected from one of the cluster nodes)

- Cluster of nodes as participants in OnlineOffline StateModel

- Set of resources with partitions.

Each node on its startup, creates a controller adds a participant if its
not existing and waits for the callbacks to handle partition rebalancing.

Please not this cluster is created on the fly multiple times a day (actual
cluster is not deleted, but new participants are removed and re-added)

Everything works fine in production, but I see that the znodes
in <clustername>/INSTANCES/INSTANCES/MESSAGES is growing.

What is <cluster_id>/INSTANCES/INSTANCES used for, is there a way for the
messages to be deleted automatically.

I see similar buildup in <cluster_id>INSTANCES/INSTANCES/CURRENTSTATES.
