Enum parquet::file::properties::BloomFilterPosition

pub enum BloomFilterPosition {
    AfterRowGroup,
    End,
}

Where in the file ArrowWriter should write Bloom filters

Basic constant, which is not part of the Thrift definition.

Variants

AfterRowGroup

Write Bloom Filters of each row group right after the row group

This saves memory by writing it as soon as it is computed, at the cost of data locality for readers

End

Write Bloom Filters at the end of the file

This allows better data locality for readers, at the cost of memory usage for writers.

Trait Implementations

impl Clone for BloomFilterPosition

fn clone(&self) -> BloomFilterPosition

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BloomFilterPosition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for BloomFilterPosition

fn eq(&self, other: &BloomFilterPosition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
