Module arrow::compute::kernels::filter [−][src]
Expand description
Defines miscellaneous array kernels.
Functions
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.
Filters an Array, returning elements matching the filter (i.e. where the values are true).
Returns a new RecordBatch with arrays containing only values matching the filter.
