I looked it up but couldn't really find information, what would you say is the difference between a "message queue", a "job queue" and a "message bus"?

- pas 4y agoI just throw them on the wall based on my experiences, maybe they have some agreed upon precise definitions, but I'm not aware :o message bus: firehose of events, (by default) no ACK. usually multi producer multi consumer. (see also DBus which is more of an RPC layer + service discovery + pub/sub via event listeners) message queue: usually between components, ACK, but no selective ACK, backpressure, might even have support for "dead letters" (letters not ACKed by any consumer) job queue: selective ACK, retry, etc. (there's also the "enterprise service bus", which is similar, but mostly implemented on things like IBM MQ)
