rerate is a redis-based ratecounter and ratelimiter
* Dead simple api
* With redis as backend, multiple rate counters/limiters can work as a cluster
* Count/Limit requests any period, 2 day, 1 hour, 5 minute or 2 second, it's up to you
* Recording requests as a histotram, which can be used to visualize or monitor
* Limit requests from single ip, userid, applicationid, or any other unique identifier
Tutorial
--------
```
package main
import (
"github.com/abo/rerate"
)
...
func main() {
// redigo buckets
pool := newRedisPool("localhost:6379", "")
buckets := rerate.NewRedigoBuckets(pool)
// OR redis buckets
// client := redis.NewClient(&redis.Options{
// Addr: "localhost:6379",
// Password: "",
// DB: 0,
// })
// buckets := rerate.NewRedisBuckets(client)
// Counter
counter := rerate.NewCounter(buckets, "rl:test", 10 * time.Minute, 15 * time.Second)
counter.Inc("click")
c, err := counter.Count("click")
// Limiter
limiter := rerate.NewLimiter(buckets, "rl:test", 1 * time.Hour, 15 * time.Minute, 100)
limiter.Inc("114.255.86.200")
rem, err := limiter.Remaining("114.255.86.200")
exceed, err := limiter.Exceeded("114.255.86.200")
