Module filter

Expand description

Defines filter kernels

Structs§

FilterBuilder: A builder to construct FilterPredicate
FilterBytes 🔒: FilterBytes is created from a source [GenericByteArray] and can be used to build a new [GenericByteArray] by copying values from the source
FilterPredicate: A filtering predicate that can be applied to an [Array]
IndexIterator 🔒: An iterator of usize whose index in [BooleanArray] is true
SlicesIterator: An iterator of (usize, usize) each representing an interval [start, end) whose slots of a bitmap [Buffer] are true.

IterationStrategy 🔒: The iteration strategy used to evaluate FilterPredicate

FILTER_SLICES_SELECTIVITY_THRESHOLD 🔒: If the filter selects more than this fraction of rows, use SlicesIterator to copy ranges of values. Otherwise iterate over individual rows using IndexIterator

build_filterDeprecated: Returns a prepared function optimized to filter multiple arrays.
filter: Returns a filtered values [Array] where the corresponding elements of predicate are true.
filter_array 🔒
filter_bits 🔒: Filter the packed bitmask buffer, with predicate starting at bit offset offset
filter_boolean 🔒: filter implementation for boolean buffers
filter_byte_view 🔒: filter implementation for byte view arrays.
filter_bytes 🔒: filter implementation for byte arrays
filter_count 🔒: Counts the number of set bits in filter
filter_dict 🔒: filter implementation for dictionaries
filter_fixed_size_binary 🔒
filter_native 🔒
filter_null_mask 🔒: Computes a new null mask for data based on predicate
filter_primitive 🔒: filter implementation for primitive arrays
filter_record_batch: Returns a filtered [RecordBatch] where the corresponding elements of predicate are true.
filter_run_end_array 🔒: Filter any supported [RunArray] based on a FilterPredicate
filter_sparse_union 🔒: filter implementation for sparse unions
filter_struct 🔒: filter implementation for structs
multiple_arrays 🔒
prep_null_mask_filter: Remove null values by do a bitmask AND operation with null bits and the boolean bits.
