US Patent 11500701 Providing a global queue through replication

A global queue service of a provider network allows clients to automatically replicate a queue to another queue of one or more other regions (creating a global queue). A local instance of the service receives a send request from a producer. In response, the local instance stores a message in a local queue and replicates the send request to a remote queue of a remote instance of the global queue service (e.g., at another region). The local instance receives a receive request from a consumer and sends the message to the consumer (without replicating the request to the remote queue). The local instance then receives a delete request from a consumer. In response, the local instance deletes the message from the local queue and replicates the delete request to the remote queue. The local instance also receives replicated requests from the remote instance and in response, applies them locally.
