issue: https://github.com/milvus-io/milvus/issues/47658 ## Summary When restoring snapshots via copy segment, the source buildIDs were reused directly, causing 1:1 map corruption in DataCoord's `segmentBuildInfo`. This PR: - Extends `CopySegmentTarget` proto with `new_build_ids` mapping (`map<int64, int64>`) - Allocates fresh buildIDs in DataCoord and passes them to DataNode - DataNode replaces buildIDs in both index file paths and metadata - Fixes indexID mismatch in `syncVectorScalarIndexes` by resolving target collection's indexID via fieldID - Shifts GC protection from indexID-based (`GetSnapshotByIndex`) to buildID-based (`GetSnapshotByBuildID`) for precise file-level protection - Updates snapshot user guide to reflect GC protection mechanism change ## Test plan - [x] Unit tests updated for `copy_segment_meta`, `snapshot_meta`, `copy_segment_task` - [x] E2E test added: snapshot restore → drop → restore again flow (`TestSnapshotRestoreDropRestoreAgain`) - [ ] CI: ut-go, integration-test, e2e pass Signed-off-by: Wei Liu <wei.liu@zilliz.com> --------- Signed-off-by: Wei Liu <wei.liu@zilliz.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |
