Objkey

Objkey is a term used in computing to denote a key that identifies an object within a collection, store, or data structure. It is not a formal standard; its exact meaning depends on the system in which it appears. Generally, an objkey is designed to be unique and stable enough to locate the object across operations.

In object storage systems, an object key serves as the object's name within a bucket. It is the primary handle used to retrieve, copy, or delete the object. Object keys are typically strings and may resemble a path or URL; many services treat them as opaque identifiers.

In software design and databases, an objKey can be an object’s identity used for indexing or mapping. It can be a numeric ID, a Universally Unique Identifier (UUID), a generated string, or a composite key made from multiple fields. The key is usually immutable after creation to preserve referential integrity.

Best practices include choosing keys that are stable, opaque, and globally unique where possible, avoiding embedding sensitive or guessable data in the key, and aligning key design with access patterns and storage constraints.
