Structs

FilterContext

FilterContext can be used to improve performance when filtering multiple data arrays with the same filter array.

Functions

filter	Returns a new array, containing only the elements matching the filter.
filter_dictionary_array	Returns a new DictionaryArray containing only those keys from the array passed as the data_array parameter, selected by the BooleanArray passed as the filter_array parameter. The values are cloned from the data_array.
filter_primitive_array	Returns a new PrimitiveArray containing only those values from the array passed as the data_array parameter, selected by the BooleanArray passed as the filter_array parameter
filter_record_batch	Returns a new RecordBatch with arrays containing only values matching the filter. The same FilterContext is re-used when filtering arrays in the RecordBatch for better performance.
