Inspect a Queue's Backlog and Consumers
queues & cron
// what it does
list shows every queue on the account; info reports one queue's backlog size, its producers, and the consumer Worker attached to it. First stop when messages aren't being processed or a backlog keeps growing — it confirms whether a consumer is even wired up.
// shell
$ wrangler queues list$ wrangler queues info <name>// gotcha
A growing backlog with no consumer usually means the [[queues.consumers]] binding was never deployed, or the consumer Worker is throwing and every batch is being retried.
