Abstract: Updates to a hierarchical data structure may be selectively replicated to other replicas of the hierarchical data structure. An update for a hierarchical data structure may be received and committed to the hierarchical data structure. A determination as to whether any other replicas of the hierarchical data structure have permission to receive the update may be made. For those replicas of the hierarchical data structure with permission to receive the update, the update may be provided to the replicas and committed to the replicas. Different types of replication techniques may be implemented, such as pull-based replication techniques or push-based replication techniques. Replication permissions for objects of the hierarchical data structure may be individually defined, in some embodiments.

Abstract: A request to add tags (e.g., labels, key-value pairs, or metadata) to resources can be digitally signed by the entity making the request, such that the source can be verified and an authorization determination made for each tag. For a request involving multiple services (or entities) that can each add tags, any tag added by a service can be included in the request and digitally signed by that service. Each service processing the request can also digitally sign the request before forwarding, so that each service signs a version of the request, which includes elements signed by other services earlier in the request chain. When the request is received to a tagging service, the service ensures that every tag was digitally signed by the appropriate authorized entity or service, and validates the signatures to ensure that no data was modified or omitted, before adding the tags to the designated resource(s).

Abstract: A user of a tag manager utilizes a tag manager to request creation of one or more zonal metadata tags. When the metadata tags are created, the tag manager updates a tag manager database to include information concerning the created metadata tags. Subsequently, the tag manager attempts to update a changes table within a discovery service database to include this information, the changes table usable by a discovery service to support regional and global tag queries. If the update of the changes table is initially unsuccessful, the tag manager may utilize a replicator to synchronize the tag manager database and the changes table when the discovery service database is once again available.

Abstract translation: 标签管理器的用户利用标签管理器来请求创建一个或多个区域元数据标签。 当元数据标签被创建时，标签管理器更新标签管理器数据库以包括关于所创建的元数据标签的信息。 随后，标签管理器尝试更新发现服务数据库中的更改表以包含此信息，发现服务可用的更改表，以支持区域和全局标签查询。 如果更改表的更新最初不成功，则当发现服务数据库再次可用时，标签管理器可以使用复制器来同步标签管理器数据库和更改表。
