Module binary_map 

ArrowBytesMap and ArrowBytesSet for storing maps/sets of values from StringArray / LargeStringArray / BinaryArray / LargeBinaryArray.

Structs

ArrowBytesMap

Optimized map for storing Arrow “bytes” types (String, LargeString, Binary, and LargeBinary) values that can produce the set of keys on output as GenericBinaryArray without copies.

ArrowBytesSet

HashSet optimized for storing string or binary values that can produce that the final set as a GenericStringArray with minimal copies.

Entry 🔒

Entry in the hash table – see ArrowBytesMap for more details

Enums

OutputType

Should the output be a String or Binary?

Constants

INITIAL_BUFFER_CAPACITY

The initial size, in bytes, of the string data

INITIAL_MAP_CAPACITY 🔒

The size, in number of entries, of the initial hash table

SHORT_VALUE_LEN 🔒

Maximum size of a value that can be inlined in the hash table

Functions

single_null_buffer 🔒

Returns a NullBuffer with a single null value at the given index
