(ql:quickload :drsnyder.beanstalk)
A native clojure beanstalkd client library. Some inspiration and ideas were taken from cl-beanstalk.
WARNING: Interface subject to change. This interface is not considered idiomatic clojure. A more “clojure” interface would probably look something like the following:
(beanstalk/with-server config-map
(use "my-tube")
(put 0 0 0 5 "hello"))
(beanstalk/with-server config-map
(watch "my-tube")
(let [job (reserve)]
(do-something-with-job)))
See also À la carte configuration in Clojure APIs.
The beanstalk client uses deftype and a protocol declaration to create a simple (socket, reader, writer) tuple. The protocol defines methods that are direct mappings to the beanstalk protocol commands. For example:
(:use com.github.drsnyder.beanstalk)
; producer
user=> (def b (new-beanstalk))
user=> (.use b "my-tube")
user=> (.put b 0 0 0 5 "hello")
...
; consumer
user=> (def b (new-beanstalk))
user=> (.watch b "my-tube")
user=> (def job (.reserve b)) ; id is (:id job), payload is (:payload job)
This library is also available on clojars. To use, add [com.github.drsnyder/beanstalk “1.0.0-SNAPSHOT”] to your dependencies.
Two examples are provided:
; start consumer
lein run -m com.github.drsnyder.beanstalk.examples.consumer
; send some data
lein run -m com.github.drsnyder.beanstalk.examples.producer -m "hello" -n 5
; send shutdown
lein run -m com.github.drsnyder.beanstalk.examples.producer -m "exit"
