etcd and zookeeper (little)
Has anyone looked at etcd? It is part of the CoreOS project but seems to
be useable independently. It is an alternative to ZooKeeper.

I’ve heard of it, but not had a chance to use it yet.
The only caveat I see is https://github.com/coreos/etcd/blob/master/Documentation/production-ready.md
Hence, a choice of ZK vs. etcd comes down to the following (from https://github.com/coreos/etcd ):
Do the use cases:
1/ Require to handle use cases that Zookeeper Atomic Broadcast (ZAB) protocol doesn’t? etcd uses Raft.
2/ Require the acclaimed “1000s of writes/s per instance”…in other words, the use cases you have in mind may outgrow ZK’s throughput
The advantage of ZK is its longer history in production (and hence, more bugs worked out of that system). There is a non-trivial value in that.
In other words, tradeoffs, tradeoffs :)

I’ve heard of it, but not had a chance to use it yet.
The only caveat I see is https://github.com/coreos/etcd/blob/master/Documentation/production-ready.md
Hence, a choice of ZK vs. etcd comes down to the following (from https://github.com/coreos/etcd ):
Do the use cases:
1/ Require to handle use cases that Zookeeper Atomic Broadcast (ZAB) protocol doesn’t? etcd uses Raft.
2/ Require the acclaimed “1000s of writes/s per instance”…in other words, the use cases you have in mind may outgrow ZK’s throughput
The advantage of ZK is its longer history in production (and hence, more bugs worked out of that system). There is a non-trivial value in that.
In other words, tradeoffs, tradeoffs :)
