Rangeid

Rangeid, sometimes written as range_id or range id, is a general term used to denote the identifier of a defined interval, segment, or pool within a system. The exact meaning and scope of a rangeid vary by domain, but it typically serves to label and distinguish one range from another for routing, allocation, or governance purposes. Range identifiers are usually numeric or alphanumeric and are intended to be unique within a given context.

In distributed data systems, rangeid commonly refers to a label assigned to a contiguous portion of the key or data space. Such a range is often managed by a set of replicas and can be split or merged as the data grows. The rangeid is used in internal metadata to route requests, monitor load, and coordinate balancing and replication. Changes to the data layout, such as splits or merges, may be accompanied by updates to the associated rangeid.

In network and IP address management, a range may refer to a pool of addresses. A rangeid can be used by management tools to distinguish between multiple address pools within a larger network or subnet, simplifying allocation and auditing of resources.

Rangeid is a context-specific concept rather than a universal standard. Its precise definition, format, and usage rules depend on the software or infrastructure in which it appears. Understanding rangeid requires consulting the documentation for the particular system to learn how it is assigned, tracked, and used in operations.
