XXH128

Overview

The XXH128 converter computes a 128-bit xxHash XXH128 hash of a string and returns it as a hexadecimal string. Like XXH3, XXH128 is a non-cryptographic hash function designed for speed. The 128-bit output reduces collision probability compared to 64-bit XXH3, making it suitable for unique identifier generation and content addressing.

Syntax

XXH128(value)

• value: the string to hash

Examples

Input

{
	"_type": "log",
	"body": {
		"short_text": "Hello, World!",
		"long_text": "The quick brown fox jumps over the lazy dog"
	},
	"resource": {...},
	"attributes": {}
}

Statement

set(attributes["hash_short"], XXH128(body["short_text"]))
set(attributes["hash_long"], XXH128(body["long_text"]))

Output

{
	"_type": "log",
	"body": {
		"short_text": "Hello, World!",
		"long_text": "The quick brown fox jumps over the lazy dog"
	},
	"resource": {...},
	"attributes": {
		"hash_short": "531df2844447dd5077db03842cd75395",
		"hash_long": "ddd650205ca3e7fa24a1cc2e3a8a7651"
	}
}

Each string produced a deterministic 32-character hexadecimal hash. The 128-bit output is twice the length of XXH3 (16 characters), providing a lower collision probability.
