## Set Queue Priority for Workflows
|
|
|
|
Enable priority on a queue to process higher-priority workflows first. Lower numbers indicate higher priority.
|
|
|
|
**Incorrect (no priority - FIFO only):**
|
|
|
|
```go
|
|
queue := dbos.NewWorkflowQueue(ctx, "tasks")
|
|
// All tasks processed in FIFO order regardless of importance
|
|
```
|
|
|
|
**Correct (priority-enabled queue):**
|
|
|
|
```go
|
|
queue := dbos.NewWorkflowQueue(ctx, "tasks",
|
|
dbos.WithPriorityEnabled(),
|
|
)
|
|
|
|
// High priority task (lower number = higher priority)
|
|
dbos.RunWorkflow(ctx, processTask, "urgent-task",
|
|
dbos.WithQueue(queue.Name),
|
|
dbos.WithPriority(1),
|
|
)
|
|
|
|
// Low priority task
|
|
dbos.RunWorkflow(ctx, processTask, "background-task",
|
|
dbos.WithQueue(queue.Name),
|
|
dbos.WithPriority(100),
|
|
)
|
|
```
|
|
|
|
Priority rules:
|
|
- Range: `1` to `2,147,483,647`
|
|
- Lower number = higher priority
|
|
- Workflows **without** assigned priorities have the highest priority (run first)
|
|
- Workflows with the same priority are dequeued in FIFO order
|
