Allow configuration for default priority

[eprothro]

Is your feature request related to a problem? Please describe.

High priority jobs (e.g. a heartbeat job) can't be easily elevated above other default priority jobs, as the default priority is the highest priority allowed.

Describe the Solution You'd Like

Allow global configuration for the default priority of a job (currently 0).

Describe Alternatives You've Considered

Explicitly setting priority for every oban job, using application configuration to set to this to a default value.

Other context

We'd like to run with job priorities aligning to high, normal, low, and background, with a default of normal.

Default priority is defined in the jobs table. The easiest way to change it for all jobs is to change the column default:

alter table("oban_jobs") do
  modify :priority, :integer, default: 1
end

Alternatively, you could set a compile time value in your application and reference it in each worker. Oban doesn't define any global values and worker definitions live entirely in your application.

perfect, thank you!

[eprothro]

While implementing, realized that the Oban.Job schema defines a default value of 0 for priority.

So, we don't have a way to globally set the default to 1 without modifying the code of every worker.

Can this Ecto schema default be removed since the DB schema defines a default?

[sorentwo]

Yes, the schema default can be removed. A PR is welcome!
