What is a major advantage of the IVF index related to large datasets?

The IVF (Inverted File) index is specifically designed to improve search efficiency in large datasets by balancing the trade-off between search speed and quality. In vast datasets, searching for specific items can become increasingly time-consuming; therefore, IVF helps by partitioning the dataset into smaller, manageable clusters or cells. This allows the search algorithm to perform a more focused search within these clusters rather than scanning the entire dataset, significantly speeding up the retrieval process.

Moreover, while maintaining speed, it still provides high-quality search results by indexing data points in a way that preserves their relationships within clusters. This balance is crucial for applications that require real-time or near-real-time search capabilities within extensive datasets, making the IVF index a suitable choice for such scenarios. In contrast, the other options do not relate directly to the core functionality and advantages of the IVF index in the context of large datasets.
