Description
Right now, index_statistics is too heavy. It's return value is a JSON String, and may contain gigabytes of information. The IVF centroids are the worst known offender.
The two key problems are:
- No type safety
- Heavy memory use and resource use
We should redesign the API to improve it.
Might be something like:
struct IndexStatistics {
general_stats: GeneralIndexStats,
specific_stats: Box<dyn Any + Send + Sync>,
}

Research direction
Start by locating the existing index_statistics entry point and reviewing the proposed IndexStatistics shape in the issue. The work is complete when the API provides type safety and avoids returning excessively large statistics such as IVF centroids, with the resulting design documented and validated by the relevant project checks.
