Struct ParquetMetadataPreparationLimits 

pub struct ParquetMetadataPreparationLimits {
    pub max_files: usize,
    pub max_retained_metadata_bytes: usize,
}

Resource limits for experimental Parquet metadata preparation.

Both limits must be greater than zero. The retained-memory limit uses the reader’s estimate of parsed Parquet metadata size, not allocator-level resident memory.

Fields

max_files: usize

Maximum number of active Parquet files to prepare.

max_retained_metadata_bytes: usize

Maximum estimated bytes of parsed Parquet metadata to retain.
