+Cloudflare queues are really straight forward to setup.
+  
+1. create the queue in the cf dashboard or via wrangler, and grab the queue name
+2. in any given cf worker project, you can define a queue `consumer`, which lets you listen to queue events, which are just arrays of arbitary json which you can define. pairing with zod we can manage complex message types.
+3. in any given cf worker you can also define a `producer`  which is the thing that can produce item to place into the queue. when setting up a producer you create a binding which can we called anything. in the Pinecone course we simply call it `QUEUE` , which gives us an worker object which we can use anywhere in our cf worker to create a message like so `c.env.QUEUE.send(queueMessage)`
+
+you can do anything when you receive the message such writing to d1 or invoking something else. queues open up the paradigm of background tasks.
