Go client for the Disque server

###Dependencies The Redigo Redis client and the YouTube Vitess resource pooling implementation are the only runtime dependencies used by disque-go. Dependencies are managed with Glide.



go get


Connection Pool

Instantiate the pool as follows:

import (


hosts := []string{""} // array of 1 or more Disque servers
cycle := 1000                       // check connection stats every 1000 Fetch's
capacity := 5                       // initial capacity of the pool
maxCapacity := 10                   // max capacity that the pool can be resized to
idleTimeout := 15 * time.Minute     // timeout for idle connections
var p *disque.Pool
p = disque.NewPool(hosts, cycle, capacity, maxCapacity, idleTimeout)

Next, get a handle to a connection from the pool, specifying a context that controls how long to wait for a connection to be retrieved:

var d *disque.Disque
var err error
d, err = p.Get(context.Background())   // get a connection from the pool
defer p.Put(d)                         // return a connection to the pool

... (use the connection to interact with Disque)...

To shutdown the connection pool, such as when the application is exiting, invoke the Close function:

p.Close()           // close the pool, waits for all connections to be returned

####Single Connection Begin by instantiating and initializing a Disque client connection:

import (


hosts := []string{""} // array of 1 or more Disque servers
cycle := 1000                       // check connection stats every 1000 Fetch's
var d *disque.Disque
var err error
d = disque.NewDisque(hosts, cycle)
err = d.Initialize()

This will yield a Disque client instance d that is configured to use the Disque server at and its cluster members, if any.

Close the Disque client connection when finished:

err = d.Close()

####Disque Operations You can push a job to a Disque queue by invoking the Push or PushWithOptions methods.

// Push with default settings
queueName := "queue_name"
jobDetails := "job"
timeout := time.Second          // take no long than 1 second to enqueue the message
var jobID string
jobID, err = d.Push(queueName, jobDetails, timeout)

// Push with custom options
options = make(map[string]string)
options["TTL"] = "60"            // 60 second TTL on the job message
options["ASYNC"] = "true"        // push the message asynchronously
jobID, err = d.PushWithOptions(queueName, jobDetails, timeout, options)

Find the length of a queue using the QueueLength function:

var queueLength int
queueLength, err = d.QueueLength(queueName)

Fetch a single job using the Fetch function:

var job *disque.Job
job, err = d.Fetch(queueName, timeout)   // retrieve a single job, taking no longer than timeout (1 second) to return

Fetch multiple jobs using the FetchMultiple function:

count := 5
var jobs []*disque.Job
jobs, err = d.FetchMultiple(queueName, count, timeout)   // retrieve up to 5 Jobs, taking no longer than timeout (1 second) to return

Retrieve details for an enqueued job before it has been acknowledged:

var jobDetails *disque.JobDetails
jobDetails, err = d.GetJobDetails(jobID)

Enqueued messages can be deleted using their Job-Id:

err = d.Delete(jobID)

Acknowledge receipt and processing of a message by invoking the Ack function:

err = d.Ack(job.JobID)

That's it (for now)!
