Examples

Send a task to a queue

from nitric.resources import queue
from nitric.api import Task

batch_queue = queue('batch').allow('sending')

payload = {}
await batch_queue.send(Task(payload=payload))

Send multiple tasks to a queue

from nitric.resources import queue
from nitric.api import Task

batch_queue = queue('batch').allow('sending')

tasks = [
  Task(payload={
      'type': 'Email',
      'to': 'hello@example.com',
      'subject': 'Notification',
      'message': 'A notification from Nitric',
  }),
  Task(payload={
      'type': 'SMS',
      'to': '+17200000000',
      'message': 'A text message from Nitric',
  })
]

await batch_queue.send(tasks)

Dealing with failures

In rare cases when sending tasks to a queue some tasks might fail to be sent. The response from send() will include an array of any tasks that failed to send. You can process this array to retry or log the error.

failed = await batch_queue.send(tasks)

for task in failed:
  print(task)
