Module arrow::compute::kernels::filter

Defines miscellaneous array kernels.

Functions

build_filter	Returns a prepared function optimized to filter multiple arrays. Creating this function requires time, but using it is faster than filter when the same filter needs to be applied to multiple arrays (e.g. a multi-column RecordBatch). WARNING: the nulls of filter are ignored and the value on its slot is considered. Therefore, it is considered undefined behavior to pass filter with null values.
filter	Filters an Array, returning elements matching the filter (i.e. where the values are true).
filter_record_batch	Returns a new RecordBatch with arrays containing only values matching the filter.
