Which storage solution is a petabyte scale, NoSQL database?BigtableFirestoreCloud SQLCloud Spanner

To determine which of the options is a petabyte-scale, NoSQL database, let’s analyze each option individually:

1. Bigtable: Google Cloud Bigtable is a NoSQL database that is designed to scale horizontally. It is optimized for large amounts of data and is suitable for analytical workloads and operational workloads. It can handle petabytes of data, making it an excellent choice for big data applications.

2. Firestore: Google Firestore is a NoSQL document database that is more suited for mobile and web app development. While it does support significant amounts of data, it is generally not classified in the same petabyte-scale category as Bigtable.

3. Cloud SQL: This is a fully-managed relational database service that supports SQL databases, such as MySQL and PostgreSQL. It is not a NoSQL database and typically does not scale to petabytes.

4. Cloud Spanner: Google Cloud Spanner is a horizontally scalable, strongly consistent, and relational database. While it can handle large datasets, it is primarily used for structured data rather than as a pure NoSQL solution.

Final Answer

The correct answer is Bigtable, as it is a petabyte-scale NoSQL database suitable for massive amounts of data.
