Choosing Google Bigtable over BigQuery is particularly advantageous for scenarios that demand high-throughput and low-latency operations involving substantial volumes of semi-structured data. Bigtable is a NoSQL database service optimized for large analytical and operational workloads, making it ideal for applications that require rapid data access and real-time analytics.

In situations involving time-series data, IoT data, or extensive read/write operations with unpredictable traffic patterns, Bigtable's architecture allows for efficient scaling and performance. It leverages its distributed nature and automatic sharding to handle high velocity and volume of data effortlessly, which is a significant advantage in use cases like analytics on real-time data streams.

Other context indicates that complex queries, extensive joins, or user-friendly data reporting are typically better suited for BigQuery, which is specifically designed for analytical querying of structured data. Hence, for the types of workloads that necessitate immediate access to large datasets without the overhead of extensive preprocessing or complicated queries, Bigtable stands out as a more appropriate choice.
