Beanstalkd bindings for python3
Beanstalk is a simple, fast work queue. Its interface is generic, but was originally designed for reducing the latency of page views in high-volume web applications by running time-consuming tasks asynchronously
pystalkd is a beanstalkd bindings targeting python3. This library is based on https://github.com/earl/beanstalkc and should be API compatible.
pip install pystalkd
or from source:
python setup.py install
>>> from pystalkd.Beanstalkd import Connection >>> c = Connection("localhost", 11300) #if no argument is given default configuration is used >>> c.put("hey!") >>> job = c.reserve(0) >>> job.body "hey!"
One of the goals is to be API compatible with beanstalkc, so this tutorial should be valid: https://github.com/earl/beanstalkc/blob/master/TUTORIAL.mkd
The main differences, API wise are:
- where number of seconds is expected pystalkd also accepts a timedelta object
- you can temporarily watch and use a tube using the with keyword
print(c.using()) # "default" with c.temporary_use("test"): print(c.using()) # "test" print(c.using()) # "default" print(c.watching()) # ["default"] with c.temporary_use("test"): print(c.watching()) # ["default", "test"] print(c.watching()) # ["default"]
- you also have access to the “bytes” API. To maintain compatibility with beanstalkc the API worked only with strings but now you can use the functions ending in “_bytes” (internally this is controlled using the raw paramater) to work directly with bytes
from os import urandom test_bytes = urandom(50) job_id = c.put_bytes(test_bytes) job = c.reserve_bytes(0) print(job.body) # b'i\x91\xdf\xf8\x1b?zj....' job_id2 = c.put("string") job2 = c.reserve_bytes(0) print(job2.body) # b'string'
Note: you can use reserve_bytes with put and get the raw string (not encoded), but the other way around might cause problems
To test with default host and port (localhost, 11300):
To test on a specific host (if port is not specified 11300 is used)
python3 test.py host [port]
