Compared against a regular zk node, works as intended:

Watch received as expected

{Type:EventNodeChildrenChanged State:Unknown Path:/ Err:<nil> Server:}

The watches are one shot in zkctl (https://github.com/coreos/zetcd/blob/master/cmd/zkctl/zkctl.go#L121) so it will exit on receiving an event. The command uses a children watch, so it only receives create/delete (EventNodeChildrenChanged) but not set. Sorry it's so cryptic, the output/documentation/behavior could use some improvement. Maybe the commands should be more similar to zkCli?

The etcd apply warnings are usually because etcd can't persist data fast enough; typically something else on the system is eating cpu/disk bandwidth.

Oh, my bad, sorry!

According to this kubernetes issue,

Any LIST query will result in this log line in etcd:

etcdserver: avoid queries with large range/delete range!

This is kind of working-as-intended.

I am guessing that zetcd uses a LIST query?

No, list is a k8s only thing. It happens whenever an rpc takes too long in the raft path.

I don't think it's related to zetcd. Try go get github.com/coreos/etcd/cmd/benchmark and see how etcd on that machine compares to the benchmarks at https://github.com/coreos/etcd/blob/master/Documentation/op-guide/performance.md#benchmarks

sorry, more newbie floundering: C:\Users\jeffr\go>go get github.com/coreos/etcd/cmd/benchmark package github.com/coreos/etcd/cmd/benchmark: cannot find package " github.com/coreos/etcd/cmd/benchmark" in any of: C:\Go\src\github.com\coreos\etcd\cmd\benchmark (from $GOROOT) c:\Users\jeffr\go\src\github.com\coreos\etcd\cmd\benchmark (from $GOPATH)

Oops, go get github.com/coreos/etcd/cmd/tools/benchmark; not sure if it will build that way on windows since some parts depend on junctions that are set up by build.bat.

Jeff17Robbins commented on June 8, 2024

That failed too. I'm too new at this to be all that helpful, sorry about that. My main interest in zetcd is to run Kafka without Zookeeper. I'm hoping I have things working well enough to start trying that.
