etcdctlv3: get range sorted by create not working as expected

[jlamillan]

etcd v3.0.12 single local node cluster.

I am trying to use etcdctl get to get a range sorted by the creation time. However, I am seeing the range seems to be always sorted in lexical order.

For example, if I create keys foo3, foo1, and foo2 in that order:

$ etcdctl put foo3 foo3val OK
$ etcdctl put foo1 foo1val OK
$ etcdctl put foo2 foo2val OK

Then try and get them, sorting by CREATE, I expect foo3, foo1, and foo2, but instead I get foo1, foo2, and foo3:

$ etcdctl get --sort-by=CREATE foo foo4
foo1 foo1val foo2 foo2val foo3 foo3val

Try

ETCDCTL_API=3 etcdctl get --sort-by=CREATE --order=ASCEND foo foo4

?

Works for me.

Probably we need better documentation around this.

@gyuho why we should provide an order here? if i tell etcdctl to sort keys by created revision, it should either sort them ascend or descend. right?

Closing via #6672.
