Which statement about Cloud Datastore is accurate?

Cloud Datastore is a fully managed NoSQL document database designed to provide high scalability and availability, making it particularly suitable for applications with varying data schemas. The accurate statement regarding Cloud Datastore is that it supports atomic transactions.

Atomic transactions ensure that a series of operations either all succeed or all fail together, which is crucial for maintaining data consistency. This ability enables developers to execute complex operations while guaranteeing that the database remains in a valid state, even in the event of failures. By allowing atomic transactions, Cloud Datastore helps in scenarios where multiple documents need to be updated as a single unit of work, enhancing reliability in applications that require that level of data integrity.

While the other options discuss features that may seem appealing, they do not accurately represent the capabilities of Cloud Datastore:

• Analytics queries can be performed, but Cloud Datastore is primarily designed for operational queries rather than complex analytical workloads.
• Cloud Datastore does not enforce referential integrity; it’s a NoSQL database and does not implement the foreign key constraints seen in relational databases.
• The database does not support complex joins or multiple inequality filters as part of its query capabilities, which differ significantly from traditional SQL databases in terms of how relationships between data are handled.

Thus, the support for atomic
