yes, my viewpoint is the same, hostname or IP has no difference for IoTDB.
The core is, we need to use node identifiers to distinguish nodes.

Hi,

I do not think we will abandon using IP. Either using IP or hostname
depends on users.
If they are sure they have a good DNS, they can use DNS;
If they like IP or the nodes do not set the DNS, they can use IP.
If they like, they can
Hi, Xiangdong,
Supporting hostname is really a good feature! However, we should consider these
cons carefully:
1. DNS request is an additional cost in nodes communication. In cloud
environment, the latency may be as large as hundreds of milliseconds(e.g.
across available regions), and local DN

Hi,
+1 for hostname.
This makes it easier to migrate the data from the failed node and start it at
another one.
And I don't think it makes much sense to allow users to intermix hostname and
IP in seed_nodes in current implementation.

Hi,
hostname +1
It makes node migration easy.
Thanks,

Hi,
Today Julian and I discussed some logic of the cluster module.
Both of us feel it strange that we replace the hostname to IP before a
cluster node starts up.
I think it is not a very common way.
hostname sometimes is very very helpful. For example, in K8S
environment, a node's hostname never
11 matches
