Constant DEFAULT_BLOOM_FILTER_NDV 

pub const DEFAULT_BLOOM_FILTER_NDV: u64 = _; // 1_048_576u64

Default value for BloomFilterProperties::ndv.

Note: this is only the fallback default used when constructing BloomFilterProperties directly. When using WriterPropertiesBuilder, columns with bloom filters enabled but without an explicit NDV will have their NDV resolved at build time to WriterProperties::max_row_group_row_count, which may differ from this constant if the user configured a custom row group size.
