# Proposed changes
Issue Number: close #xxx
## Problem Summary:
In cloud mode, when FE redirect is not used and `benodes` is not configured,
the connector discovers backends through the normal backend API. That API
returns alive BE nodes
across all clusters / compute groups.
As a result, stream load may be sent to any BE in the global backend list
instead of only the BE nodes that belong to the target compute group. This can
cause stream load
requests to be routed to the wrong compute group.
This PR makes backend discovery compute-group aware:
- Read the target compute group from stream load properties:
- `compute_group`
- fallback to legacy `cloud_cluster`
- When a target compute group is configured, discover backends from
`/rest/v2/manager/node/backends`.
- Parse backend tags and keep only alive BE nodes whose
`compute_group_name` or `cloud_cluster_name` matches the target group.
- Keep existing behavior when:
- `benodes` is explicitly configured
- FE redirect is enabled
- no compute group is configured
- Centralize this logic in `BackendUtil` and reuse it in writer, batch
stream load, and committer paths.
