Configuration¶

Worker Parameters¶

The QueueWorker class accepts these parameters:

Parameter	Default	Description
`db_name`	(required)	Database name to process jobs for
`concurrency`	`2`	Number of concurrent job execution threads
`poll_timeout`	`5`	Seconds to wait for `NOTIFY` before polling
`stale_after_seconds`	`60`	Jobs without a heartbeat for this long are considered stale and eligible for recovery
`heartbeat_interval_seconds`	`15`	How often the worker sends heartbeats for running jobs
`max_backoff_seconds`	`3600`	Maximum retry delay (exponential backoff caps here)

Environment Variables¶

Variable	Default	Description
`QUEUE_JOB_CONCURRENCY`	`2`	Worker thread pool size when using `QueueJobRunner.from_environ_or_config()`
`QUEUE_JOB__NO_DELAY`	(unset)	Set to `1` to force synchronous job execution

Runner Parameters¶

The QueueJobRunner supervises workers across multiple databases.

Parameter	Default	Description
`database_names`	(auto-discover)	List of databases to process; `None` means auto-discover
`discovery_interval_seconds`	`300`	Seconds between database discovery cycles
`maximum_consecutive_failures`	`5`	Failures within the window before a database is quarantined
`failure_window_seconds`	`300`	Time window used for failure counting
`join_timeout_seconds`	`30`	Seconds to wait for a worker thread to stop

The runner uses PostgreSQL advisory locks to prevent duplicate runners on the same databases.

Channel Throttling¶

Channels are flat string tags assigned to jobs (e.g., "root", "exports", "email"). Configure per-channel limits using the queue.limit model.

Via the UI¶

Navigate to Queue Jobs > Configuration > Channel Limits to create/edit channel limits. If job_worker_monitor is installed, you can also use Queue Jobs > Channels.

Via XML Data¶

<record id="limit_exports" model="queue.limit">
    <field name="name">exports</field>
    <field name="limit">5</field>
    <field name="rate_limit">2</field>
</record>

Fields¶

Field	Type	Default	Description
`name`	`Char`	(required)	Channel name — must match the `channel` string used in jobs
`limit`	`Integer`	`1`	Maximum concurrent jobs in this channel
`rate_limit`	`Integer`	`0`	Maximum jobs started per second (`0` = unlimited)

Default concurrency

If no queue.limit record exists for a channel, the default concurrency is 1 (one job at a time). Set limit to 0 to block the channel entirely.

Examples¶

<!-- High-throughput channel: 10 concurrent, no rate limit -->
<record id="limit_bulk" model="queue.limit">
    <field name="name">bulk</field>
    <field name="limit">10</field>
    <field name="rate_limit">0</field>
</record>

<!-- Rate-limited API channel: 3 concurrent, 1 per second -->
<record id="limit_api" model="queue.limit">
    <field name="name">api</field>
    <field name="limit">3</field>
    <field name="rate_limit">1</field>
</record>

<!-- Paused channel: no jobs will run -->
<record id="limit_paused" model="queue.limit">
    <field name="name">maintenance</field>
    <field name="limit">0</field>
</record>

Odoo Configuration¶

System Parameters¶

Key	Default	Description
`job_worker.done_job_retention_days`	`30`	Days to keep completed/failed/cancelled jobs before auto-deletion

Set via Settings > Technical > Parameters > System Parameters or:

env["ir.config_parameter"].set_param("job_worker.done_job_retention_days", "90")

odoo.conf¶

No special odoo.conf settings are required. The worker reads the standard Odoo configuration for database connection parameters.

Example minimal odoo.conf for a worker:

[options]
db_host = localhost
db_port = 5432
db_user = odoo
db_password = odoo
db_name = production
addons_path = /opt/odoo/addons,/opt/extra-addons

Security Roles¶

Two security groups control access to queue functionality:

Role	Permissions
Queue Job User	View and operate own jobs
Queue Job Manager	All user permissions + view all jobs + create/edit `queue.limit` configuration

Assign roles via Settings > Users > [User] > Other > Queue Jobs.
