deardeng opened a new pull request, #65221:
URL: https://github.com/apache/doris/pull/65221
Problem Summary: Cloud decommissioning backends can still be alive before
they reach the final decommissioned state. These backends could still be
selected by CloudReplica routing, routine load assignment, and Kafka proxy
backend selection. This change treats decommissioning backends the same as
decommissioned backends in those selection paths, while preserving current
master behavior such as direct multi-replica hashing and routine load blacklist
stale-backend cleanup.
### Release note
Cloud backend selection avoids routing new replica, routine load, and Kafka
proxy work to decommissioning backends.

- mvn checkstyle:check -pl fe-core
- git diff --cached --check
- Behavior changed: Yes. Cloud BE selection now excludes
decommissioning/decommissioned backends in the affected routing and load paths.
- Does this need documentation: No
