you've made decent-ish posts in other threads, how are you so retarded that you can't understand a simple key-value store, and post this thread without knowing what zookeeper is

people use etcd when they've moved all their poo poo to dockers and ec2 instances and need some way to figure out which machine is the current redis instance because they can't just put their simple app on the same machine as the db it uses because then they don't get to play with cool toys like etcd and kubernetes and docker

if you can't completely blow away your redis cluster and have the software continue to function as-normal-but-a-bit-slower, you are using redis incorrectly

i've seen plenty of damage done by devs who can rattle off an answer to "what is xyzzy" in an interview but don't know when & why to use it

can an etcd cluster be deployed across multiple zones? iirc that's why kubernetes' control plane is still single zoned.

Gazpacho posted:i'm trying to improve my leet container skills by learning about etcd but nobody seems to know just what it might be used for serious response: like others have said, etcd is a distributed key-value store. but so are a lot of things; s3 is a distributed key-value store and its semantics are quite a bit different from etcd. one of the benefits of etcd (and why they talk about their consensus algorithm) is that it guarantees that your reads and your writes occur in a particular order regardless of which replica you're talking to. this means (as compared to s3) that while what a read from replicas might return a stale state (because networks and time happen), you will never see older states than whatever you've seen currently. additionally, etcd provides multi-key transactions that would allow you to update multiple service(s) (or whatever) in lock-step and with guarantees (ex. this value was n before i set it to n+1). this is cool and good when you need it.
