A collection of id generation methods
Snowflake
Node varies from 0 to 32 Datacenter varies from 0 to 32
local sfl = require 'id.snowflake'
local gen = sfl:new{ node = 1; datacenter = 2; }
local id = gen:id()
...621246523426082816ULL
DSG (Distributed Sequence Generator): Simplified version of Snowflake
Algorithm taken from article "Generating unique IDs in a distributed environment at high scale"
Node varies from 0 to 1023
local dsg = require 'id.dsg'
local gen = dsg:new{ node = 1; }
local id = gen:id()
...595018701653151744ULL
ULID
Implementaion of ULID
local ulid = require 'id.ulid'
local gen = ulid:new()
local id = gen:id()
...01DEN8879B47JBKVCJBW7DV3F8
Icecap
Something between snowflake and ulid (It looks like ulid, and made from 50 bits of time, 10 bits of node id and 60 bits of random)
local icecap = require 'id.icecap'
local gen = icecap:new{node = 1}
local id = gen:id()
...01DFTJ1B3E01Y9HRTHDAFZY3
Base 58 UUID
(Requires base58 library)
local uuid58 = require 'id.uuid58'
local gen = uuid58:new()
local id = gen:id()
...4fuuF9Mg7DfsgQU8sTneQw
May be customized with prefix
local uuid58 = require 'id.uuid58'
local gen = uuid58:new{ prefix = 'P' }
local id = gen:id()
...P3SdUvhcfLjMHbsG8naW9gB
Base 58 Random
(Requires base58 library)
local r58 = require 'id.r58'
local gen = r58:new()
local id = gen:id()
...vfcxxHeBxp7XatJcrXyCpA
May be customized with prefix and size (in bytes)
local r58 = require 'id.r58'
local gen = r58:new{ prefix = 'P'; size = 32 }
local id = gen:id()
