Answer: 1 TB

## Explanation Cloud Bigtable is designed for large-scale, high-throughput workloads and is optimized for storing massive amounts of data. The recommended minimum amount of stored data for Cloud Bigtable is **1 TB**. ### Key Points: - **1 TB minimum**: Cloud Bigtable is optimized for datasets of 1 TB or larger - **Performance optimization**: Smaller datasets may not fully utilize Bigtable's distributed architecture and may experience suboptimal performance - **Cost efficiency**: For datasets smaller than 1 TB, other Google Cloud storage options like Cloud SQL, Firestore, or Cloud Spanner might be more cost-effective - **Use case alignment**: Bigtable is ideal for applications requiring low-latency access to large amounts of structured data, such as time-series data, IoT data, or financial data For datasets smaller than 1 TB, consider alternative storage solutions that better match the scale and performance requirements of your application.
