Struct FileStats 

pub struct FileStats<S> {
    pub id: FileId,
    pub partition: String,
    pub sketch: S,
}

File-level sketch summary — the Puffin-blob equivalent.

Generic over the caller’s sketch type S. The sketch is the aggregate over the records within the file; the catalog backend (in-memory today, Iceberg+Puffin tomorrow) is responsible for that aggregation at write time.

Fields

id: FileId

Stable file identifier.

partition: String

Partition tag. Convention is caller-defined; the catalog only uses string equality for filtering.

sketch: S

Caller-supplied summary statistics (HLL, variance, histograms, etc.).
