Step 1: identify that you and at least one other node are separated by distance, and some lossy communication channel, and therefore form a distributed system.

Step 1: identify that you and at least one other node are separated by distance, and some lossy communication channel, and therefore form a distributed system.
Step 2: propose a source of truth that everyone can listen to. Hearing the same facts in the same order should put everyone in the same state (eventual consistency)
Step 3 (you are here): try to do better than EC, by merging the external queue into one of the nodes, making it the master.
Step 4: Now there's no distance between the nodes, so no need to solve the distributed systems problem and you can retire the queue.
- convolvatron 4mo agoeventual consistency as generally used doesn't guarantee that events are presented in the same order. I use 'monotonic consistency' for that, but idk how common that is.
- mrkeen 4mo agoYes, same-ordering gives you EC, not the other round.
- AlotOfReading 4mo agoOrder independence/monotonicity is strong EC rather than regular EC.
