Use of BEANSTALKD (Golang)

This is a creation in Article, where the information may have evolved or changed. Recently, a new message queue has to be introduced, preferably a professional, simple, message-not-lost feature, without introducing too much complexity.
Especially in the present single-handedly case. Then I found out that BEANSTALKD seems to be what I need.
The BEANSTALKD supports task priorities (priority), latency (delay), timeout (time-to-run) and reservation (buried),
Support Binlog at the same time. The final speed is also possible.
Read the next source, C language code is small and clear. The author maintained from 07 to 14, star is also very high, the quality should be guaranteed.
The queue author provides the go client, which can be seen from the list of author projects that has written a lot of go-related things, and it seems that go is popular with background development.

BEANSTALKD home in this: HTTP://KR.GITHUB.IO/BEANSTALKD

Write an example of the invocation as follows.

Use Beanstool to view queue status

can also refer to I write the following two paragraphs, to check.

AR, er: = C.listtubes () if er! = nil {fmt. Println ("[Example]  er:", er)} else {for I, V: = Range ar {fmt. Println ("[Example] listtubes  i:", I, "V:", v) c.tube.name = vid, body, err: = C.reserve (5 * time). Second) If err! = Nil {fmt. Println ("[Example] Err:", err, "Name:", c.tube.name) continue} else {FMT. Println ("[Example] Job:", id) fmt. Println ("[Example] Body:", string (body))}}}func Tubestatus (c *beanstalk. Conn) {fmt. Println ("[tubestatus]/////////////////////////") fmt. Println ("Tube (", C.tube.name, ") Stats:") m, er: = c.tube.stats () if er! = nil {fmt. Println ("[Tubestatus] Err:", er)} else {for k, V: = range m {fmt. Println (k, ":", v)}}fmt. Println ("[tubestatus]/////////////////////////")}

From the test, beanstalkd enough to meet my current needs.
