golang redis hashmap using key shards

Installation

~ $ go get -u github.com/paulusrobin/go-redis-hashmap-key-shards

Example

var redis RedisHashMap
var log Log
var shards uint32
cache, err := hashmap_shards.NewHashMapShards(redis, log, shards)
if err != nil {
    log.Error(err)
    panic(err)
}

_ = cache.HMSetWithExpiration("example", map[string]int{
    "hello": 1,
}, time.Minute)

_ = cache.HSetWithExpiration("example", "world", 2, time.Minute)

if val, err := cache.HMGet("example", "hello", "world"); err == nil {
    fmt.Println(val)
}

if val, err := cache.HGetAll("example"); err == nil {
    fmt.Println(val)
}
