Enum parquet::file::properties::BloomFilterPosition
source · pub enum BloomFilterPosition {
AfterRowGroup,
End,
}
Expand description
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.
