Gosnowflake
Distributed thread-safe UID generator implemented according to Twitter Snowflake algorithm
Feature
Thread-Safe UID generator
Green pluggable, no reliance on redis,mysql, no status
Suitable for distributed systems
Implementing the Twitter Snowflake theory
Description
0 41 51 64+---------------+----------------+-----------+|timestamp(ms) | worker node id | sequence |+---------------+----------------+-----------+id = timestamp | workerid | sequence (eg. 1451063443347648410)
Consists of three parts combined with operations, namely millisecond-level timestamps, machine Workerid, and serial numbers to resolve conflicts
Installation
go get github.com/zheng-ji/goSnowFlake
Example
import ( "fmt" "github.com/zheng-ji/goSnowFlake")func main() { // Params: Given the workerId, 0 < workerId < 1024 iw, err := goSnowFlake.NewIdWorker(1) if err!= nil { fmt.Println(err) } for i := 0; i < 100; i++ { if id, err := iw.NextId(); err != nill { fmt.Println(id) } }}
