Let's see, let's pick some checkboxes.
(x) you pushed the actual problem to another layer of the system
(x) you're actually building an AP system
- hot_gril 2y agoYou're building a ??? system. Either CP or AP depending on what random values got put into some config.

- Spivak 2y agoSpecifically they pushed the problem to the load-balancer so they get to check this one too. (x) your solution requires a central authority that cannot be unavailable I'm amazed the author doesn't consider that the load-balancers in this situation are effectively acting as non-voting witnesses and that the whole system hinges on the lbs being able to correctly determine the healthy nodes. In a single-master setup the network partition that cuts the line between the lbs and the current master (but nothing else) is a fun one. Everything would be fine if you could promote a new master but who's gonna tell em'?
- rdtsc 2y agoThat's a good point. It describes the situation better than my checklist.
