Struct ParquetMetadataPreparationReport 

#[non_exhaustive]
pub struct ParquetMetadataPreparationReport {
    pub files_prepared: usize,
    pub estimated_retained_metadata_bytes: usize,
    pub preparation_duration: Duration,
    pub read_metrics: DeltaScanMetricsSnapshot,
}

Measurements recorded while preparing one table’s Parquet metadata.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

files_prepared: usize

Number of active Parquet files prepared.

estimated_retained_metadata_bytes: usize

Estimated bytes retained by the parsed Parquet metadata.

preparation_duration: Duration

Time spent fetching and parsing Parquet metadata after scan planning completed.

read_metrics: DeltaScanMetricsSnapshot

Reader metrics collected by the preparation scan plan.
