0.9.0: Queueing lock

Breaking changes

• Rename PostgresConnector into AiopgConnector (#225):

  The class PostgresConnector became AiopgConnector. The only change is the name.

Migrations

• https://github.com/peopledoc/procrastinate/blob/0.9.0/procrastinate/sql/migrations/delta_0.8.1_001_add_queueing_lock_column.sql

Features

• Add notion of "queueing lock" (#219):

  Queueing locks can ensure periodic jobs do not accumulate in the queue: at any given time, only a single job with a given queueing lock can be waiting.

Postgres Connector

Breaking compatibility ⚠️

Now, to setup your postgres connector you can do:

connector = procrastinate.PostgresConnector(
    dsn="postgres://user:password@host:port/dbname"
)
# or if you already have an aiopg pool:
connector = procrastinate.PostgresConnector()
connector.set_pool(my_pool)

Associated PRs:

0.4.0: From Job Store to Connector

Breaking changes

App is now initialized with a PostgresConnector object instead of a PostgresJobStore.

Change your code from:

app = procrastinate.App(job_store=procrastinate.PostgresJobStore(dsn="..."))

to

app = procrastinate.App(connector=procrastinate.PostgresConnector(dsn="..."))

⚠️ We're going to change a few details around that in the next versions, if you want to avoid frequent changes and you don't need this release, it might be worth waiting for the next ones. We'll advertise when we thing the App API is likely stable.
