-------------------------------------
Summary: Adding observers dynamically without server id
Key: ZOOKEEPER-2879
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2879
Project: ZooKeeper
Issue Type: Improvement
Components: quorum
Affects Versions: 3.6.0
Reporter: Fangmin Lv
Assignee: Fangmin Lv
Dynamic config requires observer has unique server id, which means we cannot
simply add observer with dynamic server id -1. For large observer cluster, it's
much more easier to add
observer without unique server id if it doesn't need to be promoted to
participant. Also, it will
make dynamic config more efficient, we don't need to store and send the long
list of observers
during re-config.
