• cast_utils
  Parser implementations for converting strings to Arrow types
• cmp
  Comparison kernels for Arrays.
• comparison
  Comparison kernels for Arrays.
• concat
  Defines concat kernel for ArrayRef
• concat_elements
  Provides utility functions for concatenation of elements in arrays.
• filter
  Defines filter kernels
• interleave
  Interleave elements from multiple arrays
• length
  Defines kernel for length of string arrays and binary arrays
• nullif
  Implements the nullif function for Arrow arrays.
• numeric
  Defines numeric arithmetic kernels on PrimitiveArray, such as add
• partition
  Defines partition kernel for ArrayRef
• rank
  Provides rank function to assign a rank to each value in an array
• regexp
  Defines kernel to extract substrings based on a regular expression of a [Large]StringArray
• sort
  Defines sort kernel for ArrayRef
• substring
  Defines kernel to extract a substring of an Array Supported array types: GenericStringArray, GenericBinaryArray, FixedSizeBinaryArray, DictionaryArray
• take
  Defines take kernel for Array
