package redis

import "github.com/go-redis/redis"

Package redis implements a Redis client.

Example (CustomCommand)

Code: 

Get := func(rdb *redis.Client, key string) *redis.StringCmd {
    cmd := redis.NewStringCmd("get", key)
    rdb.Process(cmd)
    return cmd
}

v, err := Get(rdb, "key_does_not_exist").Result()
fmt.Printf("%q %s", v, err)

Output:

"" redis: nil
Example (CustomCommand2)

Code: 

v, err := rdb.Do("get", "key_does_not_exist").String()
fmt.Printf("%q %s", v, err)

Output:

"" redis: nil
Example (Instrumentation)

Code: 

rdb := redis.NewClient(&redis.Options{
    Addr: ":6379",
})
rdb.AddHook(redisHook{})

rdb.Ping()

Output:

starting processing: <ping: >
finished processing: <ping: PONG>

// expiration time.
err := rdb.Set("key", "value", 0).Err()
if err != nil {
    panic(err)
}

// key2 will expire in an hour.
err = rdb.Set("key2", "value", time.Hour).Err()
if err != nil {
    panic(err)
}

Subscribe subscribes the client to the specified channels. Channels can be omitted to create empty subscription. Note that this method does not wait on a response from Redis, so the subscription may not be active immediately. To force the connection to wait, you may call the Receive() method on the returned *PubSub like so: 

sub := client.Subscribe(queryResp)
iface, err := sub.Receive()
if err != nil {
    // handle error
}

// Should be *Subscription, but others are possible if other actions have been
// taken on sub since it was created.
switch iface.(type) {
case *Subscription:
    // subscribe succeeded
case *Message:
    // received first message
case *Pong:
    // pong received
default:
    // handle error
}

ch := sub.Channel()

// Transactionally increments key using GET and SET commands.
increment := func(key string) error {
    txf := func(tx *redis.Tx) error {
        // get current value or zero
        n, err := tx.Get(key).Int()
        if err != nil && err != redis.Nil {
            return err
        }

        // actual opperation (local in optimistic lock)
        n++

        // runs only if the watched keys remain unchanged
        _, err = tx.Pipelined(func(pipe redis.Pipeliner) error {
            // pipe handles the error case
            pipe.Set(key, n, 0)
            return nil
        })
        return err
    }

    for retries := routineCount; retries > 0; retries-- {
        err := rdb.Watch(txf, key)
        if err != redis.TxFailedErr {
            return err
        }
        // optimistic lock lost
    }
    return errors.New("increment reached maximum number of retries")
}

var wg sync.WaitGroup
wg.Add(routineCount)
for i := 0; i < routineCount; i++ {
    go func() {
        defer wg.Done()

        if err := increment("counter3"); err != nil {
            fmt.Println("increment error:", err)
        }
    }()
}
wg.Wait()

n, err := rdb.Get("counter3").Int()
fmt.Println("ended with", n, err)

Output:

Pipeliner is an mechanism to realise Redis Pipeline technique.

Pipelining is a technique to extremely speed up processing by packing operations to batches, send them at once to Redis and read a replies in a singe step. See https://redis.io/topics/pipelining

Pay attention, that Pipeline is not a transaction, so you can get unexpected results in case of big pipelines and small read/write timeouts. Redis client has retransmission logic in case of timeouts, pipeline can be retransmitted and commands can be executed more then once. To avoid this: it is good idea to use reasonable bigger read/write timeouts depends of your batch size and/or use TxPipeline.

type Pong Uses

❖

    Payload string
}

Pong received as result of a PING command issued by another client.

func (*Pong) String Uses

❖

type PoolStats Uses

❖

type PubSub Uses

❖
type PubSub struct {
    // contains filtered or unexported fields
}

PubSub implements Pub/Sub commands as described in http://redis.io/topics/pubsub. Message receiving is NOT safe for concurrent use by multiple goroutines.

PubSub automatically reconnects to Redis Server and resubscribes to the channels in case of network errors.

Example

Code: 

pubsub := rdb.Subscribe("mychannel1")

// Wait for confirmation that subscription is created before publishing anything.
_, err := pubsub.Receive()
if err != nil {
    panic(err)
}

// Go channel which receives messages.
ch := pubsub.Channel()

// Publish a message.
err = rdb.Publish("mychannel1", "hello").Err()
if err != nil {
    panic(err)
}

time.AfterFunc(time.Second, func() {
    // When pubsub is closed channel is closed too.
    _ = pubsub.Close()
})

// Consume messages.
for msg := range ch {
    fmt.Println(msg.Channel, msg.Payload)
}

Output:

mychannel1 hello

func (*PubSub) Channel Uses

❖
func (c *PubSub) Channel() <-chan *Message

Channel returns a Go channel for concurrently receiving messages. The channel is closed together with the PubSub. If the Go channel is blocked full for 30 seconds the message is dropped. Receive* APIs can not be used after channel is created.

go-redis periodically sends ping messages to test connection health and re-subscribes if ping can not not received for 30 seconds.

func (*PubSub) ChannelSize Uses

❖
func (c *PubSub) ChannelSize(size int) <-chan *Message

ChannelSize is like Channel, but creates a Go channel with specified buffer size.

func (*PubSub) ChannelWithSubscriptions Uses

❖
func (c *PubSub) ChannelWithSubscriptions(size int) <-chan interface{}

ChannelWithSubscriptions is like Channel, but message type can be either *Subscription or *Message. Subscription messages can be used to detect reconnections.

ChannelWithSubscriptions can not be used together with Channel or ChannelSize.

❖

func (*PubSub) Ping Uses

❖
func (c *PubSub) Ping(payload ...string) error

func (*PubSub) Receive Uses

❖
func (c *PubSub) Receive() (interface{}, error)

Receive returns a message as a Subscription, Message, Pong or error. See PubSub example for details. This is low-level API and in most cases Channel should be used instead.

Example

Code: 

pubsub := rdb.Subscribe("mychannel2")
defer pubsub.Close()

for i := 0; i < 2; i++ {
    // ReceiveTimeout is a low level API. Use ReceiveMessage instead.
    msgi, err := pubsub.ReceiveTimeout(time.Second)
    if err != nil {
        break
    }

    switch msg := msgi.(type) {
    case *redis.Subscription:
        fmt.Println("subscribed to", msg.Channel)

        _, err := rdb.Publish("mychannel2", "hello").Result()
        if err != nil {
            panic(err)
        }
    case *redis.Message:
        fmt.Println("received", msg.Payload, "from", msg.Channel)
    default:
        panic("unreached")
    }
}

// sent message to 1 rdb
// received hello from mychannel2

func (*PubSub) ReceiveMessage Uses

❖
func (c *PubSub) ReceiveMessage() (*Message, error)

ReceiveMessage returns a Message or error ignoring Subscription and Pong messages. This is low-level API and in most cases Channel should be used instead.

func (*PubSub) ReceiveTimeout Uses

❖
func (c *PubSub) ReceiveTimeout(timeout time.Duration) (interface{}, error)

ReceiveTimeout acts like Receive but returns an error if message is not received in time. This is low-level API and in most cases Channel should be used instead.

func (*PubSub) String Uses

❖
func (c *PubSub) String() string

func (*PubSub) Subscribe Uses

❖
func (c *PubSub) Subscribe(channels ...string) error

Subscribe the client to the specified channels. It returns empty subscription if there are no channels.

func (*PubSub) Unsubscribe Uses

❖
func (c *PubSub) Unsubscribe(channels ...string) error

Unsubscribe the client from the given channels, or from all of them if none is given.

type Ring Uses

❖
type Ring struct {
    // contains filtered or unexported fields
}

Ring is a Redis client that uses consistent hashing to distribute keys across multiple Redis servers (shards). It's safe for concurrent use by multiple goroutines.

Ring monitors the state of each shard and removes dead shards from the ring. When a shard comes online it is added back to the ring. This gives you maximum availability and partition tolerance, but no consistency between different shards or even clients. Each client uses shards that are available to the client and does not do any coordination when shard state is changed.

Ring should be used when you need multiple Redis servers for caching and can tolerate losing data when one of the servers dies. Otherwise you should use Redis Cluster.

func NewRing Uses

❖
func NewRing(opt *RingOptions) *Ring

Code: 

rdb := redis.NewRing(&redis.RingOptions{
