Overview
WUID
is a universal unique identifier generator.WUID
is much faster than traditional UUID. EachWUID
instance can even generate 100M unique identifiers in a single second.- In the nutshell,
WUID
generates 64-bit integers in sequence. The high 28 bits are loaded from a data source. By now, Redis, MySQL, MongoDB and Callback are supported. - The uniqueness is guaranteed as long as all
WUID
instances share a same data source or each group of them has a different section ID. WUID
automatically renews the high 28 bits when the low 36 bits are about to run out.WUID
is thread-safe, and lock free.- Obfuscation is supported.

Usages

Callback
import "github.com/edwingeng/wuid/callback/wuid"
callback := func() (int64, func(), error) {
var h28 int64
// ...
return h28, nil, nil
}
// Setup
w := NewWUID("alpha", nil)
err := w.LoadH28WithCallback(callback)
if err != nil {
panic(err)

Mysql Table Creation
CREATE TABLE IF NOT EXISTS `wuid` (
`h` int(10) NOT NULL AUTO_INCREMENT,
`x` tinyint(4) NOT NULL DEFAULT '0',
PRIMARY KEY (`x`),
UNIQUE KEY `h` (`h`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Options
WithSection
brands a section ID on each generated number. A section ID must be in between [0, 7].WithStep
sets the step and the floor for each generated number.WithObfuscation
enables number obfuscation.
Attentions
It is highly recommended to pass a logger to wuid.NewWUID
and keep an eye on the warnings that include "renew failed". It indicates that the low 36 bits are about to run out in hours to hundreds of hours, and the renewal program failed for some reason. WUID
will make many renewal attempts until succeeded.
