Configuration

Cloudflare Queues can be configured using Wrangler, the command-line interface for Cloudflare’s Developer Platform, which includes Workers, R2, and other developer products.

Each Worker has a wrangler.toml configuration file that specifies environment variables, triggers, and resources, such as a Queue. Use the options below to configure your Queue.

​​ Producer

These options should be used when a Worker wants to send messages to a Queue.

[[queues.producers]]
queue = "my-queue"
binding = "MY_QUEUE"
  • queuestring

    • The name of the Queue.
  • bindingstring

    • The name of the binding, which is a JavaScript variable.

​​ Consumer

These options should be used when a Worker wants to receive messages from a Queue. Refer to Limits to review the maximum values for each of these options.

[[queues.consumers]]
queue = "my-queue"
max_batch_size = 10
max_batch_timeout = 30
max_retries = 10
dead_letter_queue = "my-queue-dlq"
  • queuestring

    • The name of the Queue.
  • max_batch_sizenumber optional

    • The maximum number of messages allowed in each batch.
  • max_batch_timeoutnumber optional

    • The maximum number of seconds to wait until a batch is full.
  • max_retriesnumber optional

    • The maximum number of retries for a message, if it fails or retryAll() is invoked.
  • dead_letter_queuestring optional

    • The name of another Queue to send a message if it fails processing at least max_retries times.
    • If a dead_letter_queue is not defined, messages that repeatedly fail processing will eventually be discarded.
    • If there is no Queue with the specified name, it will be created automatically.
