Introduction to Asynchronous Processing and Message Queues
网页2021年12月31日 · Synchronous vs Asynchronous Processing. Synchronous requests block the execution thread of the client, forcing them to wait for the response to come before they can perform another action. On the other hand, asynchronous requests do not block and allow for more work to be done in a given time.

Asynchronous Messaging, Part 2: Durable Queues - Stephen Cleary
网页2021年1月14日 · Asynchronous messaging must use a queue whose messages survive shutdown. This is good enough for many (most?) applications. A more durable (or more reliable) queue would be one that writes to multiple disks. This allows the messages to also survive a single disk failure.
Queues — Python 3.9.20 documentation
网页2020年3月9日 · asyncio queues are designed to be similar to classes of the queue module. Although asyncio queues are not thread-safe, they are designed to be used specifically in async/await code. Note that methods of asyncio queues don’t have a timeout parameter; use asyncio.wait_for() function to do queue operations with a timeout.
