HashXXmod
Purpose
Generates a number which is mod of given string’s hash.
hash32mod(literal_string, modulo) / hash32mod(literal_string, modulo, seed)
- Generates a number which is calculated on (32 bit hash of the given string % modulo)
If modulo is not a valid number, then 0 is returned.
If modulo is 0, then 0 is returned.
Seed is an optional parameter with default = 0.
If seed is not a valid unsigned number, then 0 is returned.
hash64mod(literal_string, modulo) / hash64mod(literal_string, modulo, seed)
- Generates a number which is calculated on (64 bit hash of the given string % modulo)
If modulo is not a valid number, then 0 is returned.
If modulo is 0, then 0 is returned.
Seed is an optional parameter with default = 0.
If seed is not a valid unsigned number, then 0 is returned.
Warning
Default hash implementation is non-crypto.
To use xxhash enable compile time flag.
Example
module(load="fmhash")
if (hash64mod($!msg!request_id, 100) <= 30) then {
//send out
}
