Struct ReadOptions

Source 
pub struct ReadOptions {
    predicates: Vec<ReadGroupPredicate>,
    enable_page_index: bool,
    props: ReaderProperties,
}
Expand description

A collection of options for reading a Parquet file.

Currently, only predicates on row group metadata are supported. All predicates will be chained using ‘AND’ to filter the row groups.
