Struct StreamingOptions 

pub struct StreamingOptions {
    pub reservoir_capacity: usize,
    pub distinct_cap: usize,
    pub compute_duplicates: bool,
    pub seed: u64,
}

Options for profile_csv_streaming_with.

Fields

reservoir_capacity: usize

Reservoir size for quantile/histogram sampling per column (default 10_000). Tables with at most this many rows are profiled exactly.

distinct_cap: usize

Maximum tracked distinct values per categorical column (default 100_000). Beyond this, unique becomes a documented lower bound.

compute_duplicates: bool

Track exact duplicate rows (default false): costs one hash-set entry per row.

seed: u64

Seed for reservoir sampling (default 0x9E37_79B9_7F4A_7C15).
