----------------------------------
Summary: Add admin server command to shed client connections by
percentage
Key: ZOOKEEPER-5015
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-5015
Project: ZooKeeper
Issue Type: New Feature
Components: server
Affects Versions: 3.10.0
Reporter: Li Wang
Implement a new admin server command (i.e. {{shed_connections)}} that allows
operators to drop a specified percentage of client connections for load
management and operational control.
Key Use Cases:
* *Fixing client connection imbalance* caused by rolling restarts or server
failures, where connections concentrate on remaining servers
* *Preventing thundering herd effects* during planned server maintenance by
gradually redistributing connections before taking a server offline
* *Enabling proportional load reduction* on overloaded servers (e.g., leaders
experiencing high CPU/memory usage) to maintain cluster stability
