-----------------------------------------
Summary: Symbolic nodes
Key: ZOOKEEPER-1511
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1511
Project: ZooKeeper
Issue Type: Wish
Reporter: Sheetal Parade
Zookeeper currently allows two type of nodes: EPHEMERAL and PERSISTENT. If the
node or node data needs to be referenced from other nodes, entire node needs to
be copied to new location. There is no relation between the original and copied
nodes. Symbolic nodes like in unix directory structure would keep the nodes and
node data in sync.
Use case:
While implementing managed clusters for micro shards strategy, client can
register by creating Ephemeral nodes. The master process can then create new
symbolic nodes along with other clients nodes for next set of processes to
watch. If the client goes down, the ephemeral node cleans itself along with
symbolic node. There could be different set of watchers on symbolic nodes which
would then get notified.
