Store builds with the legacy GraphID preflight now refuse affected data before allocation, cold partition opening, Raft startup or staged snapshot activation. The English and Chinese HStore configuration pages explain these checks and how to preserve DB versions, metadata, WAL and snapshot evidence after refusal.

Paired with hugegraph/hugegraph#301. The ID format stays unchanged; automatic ownership repair and complete deployment upgrades require separate validation.

Validation: existing link checks and diff checks passed; one independent documentation review found no actionable issues.

Summary by CodeRabbit

  • 文档
    • 补充旧版 Graph ID 升级预检说明:该保护仅适用于包含相关实现的 Store 构建,较早的 1.8 构建不保证具备此检查。检测到保留的旧数据或可能遮蔽有效版本的不完整数据库版本时,部分启动、分配图 ID 或激活快照的操作会被拒绝。
    • 说明拒绝操作时应保留数据库版本及相关数据;预检不会迁移或修复数据,且启动过程中 Store/Raft 位置元数据可能已更新。补充升级指南链接。

Implementation overview

Conceptual illustration of the paired ASF Docs PR apache#523 at the same source revision: reject legacy GraphID storage before startup. This diagram does not establish migration or upgrade acceptance.

GraphID startup refuses legacy storage before opening

- describe cold-open and replay checks
- preserve evidence when preflight refuses
- clarify upgrade and recovery boundaries

Independent two-reviewer cross-check: 9/10 for this documentation-only change. English and Chinese guidance agree with the pinned preflight implementation and clearly preserve DB versions, metadata, WAL and snapshots, prohibit guessed ownership/mapping deletion, and distinguish refusal from migration. No actionable documentation finding. The implementation’s custom-column-family-options issue (hugegraph/hugegraph#301) and complete 1.7 upgrade/replay/snapshot/per-replica rollback acceptance remain separate open gates.

- point both language pages to the validated source
- retain the established upgrade warning text
- keep the code and website guidance aligned
- scope the guard to builds containing the paired fix
- link the Apache implementation and upgrade guide
- add matching English and Chinese section headings
