Postgres Broker for Dramatiq Task Queue
pip install dramatiq-pg==0.6.0
Dramatiq is a simple task queue implementation for Python3. dramatiq-pg provides a Postgres-based implementation of a dramatiq broker.
Note that dramatiq assumes tasks are idempotent. This broker makes the same assumptions for recovering after a crash.
$ pip install dramatiq-pg psycopg2-binary
Ensure you have either psycopg2 or psycopg2-binary installed.$ psql -f dramatiq_pg/schema.sql
import dramatiq
import psycopg2.pool
from dramatiq_pg import PostgresBroker
dramatiq.set_broker(PostgresBroker(i))
@dramatiq.actor
def myactor():
...
Now declare/import actors and manage worker just like any dramatiq setup. An example script is available, tested on CI.
The CLI tool dramatiq-pg
allows you to requeue messages, purge old messages
and show stats on the queue. See --help
for details.
Dramatiq-pg documentation is hosted on GitLab and give you more details on deployment and operation of Postgres as a Dramatiq broker.
If you encounter a bug or miss a feature, please open an issue on GitLab with as much information as possible.
dramatiq_pg is available under the PostgreSQL licence.
