deardeng opened a new pull request, #67214: URL: https://github.com/apache/doris/pull/67214
pick from https://github.com/apache/doris/pull/65173 This PR introduces a public backend selection extension framework for query, load, and replica-repair scheduling paths. The public interfaces are aligned with the downstream implementation so that downstream extensions can be maintained without carrying kernel API differences. Apache Doris does not provide or register an affinity BackendSelectionProvider. The default community provider is strictly no-op, preserving existing query scheduling, load candidate ordering, placement, and replica-repair source selection behavior. This PR does not introduce resource-group affinity implementation, enterprise provider, enterprise configuration, or other enterprise-only behavior. ### What problem does this PR solve?
