Features

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.
