Datastorecompatible

Datastorecompatible is an adjective used to describe software systems, services, or adapters that implement or conform to the Datastore API, enabling applications written for Google Cloud Datastore to operate against alternative backends with minimal changes. In practice, a Datastorecompatible component provides the same data model—entities organized into kinds with keys and properties—and supports core operations such as creating, reading, updating, and deleting entities, as well as querying, indexing, transactions, and ancestor paths.

Implementation and scope

Datastorecompatibility is often realized as a compatibility layer or adapter that translates between the Datastore API and the underlying storage engine. This layer aims to preserve API compatibility so that client libraries and code written for Datastore can function without substantial modification. Some platforms advertise Datastore compatibility to facilitate migrations to other storage solutions or to enable cross-cloud development using a consistent API surface.

Use cases and considerations

Common use cases include easing migrations from Datastore to Firestore in Datastore mode, enabling multi-cloud development, and supporting testing or local development with familiar Datastore-like semantics. While Datastorecompatibility can simplify integration, it may introduce limitations. Not all Datastore features or performance guarantees are guaranteed to carry over, and differences in transaction semantics, consistency models, or index management may arise.
