nickva commented on issue #3887: URL: https://github.com/apache/couchdb/issues/3887#issuecomment-1756164815 Clustering is a way to connect multiple Apache CouchDB nodes using Erlang's native clustering mechanism over TCP connections. At the HTTP API level it looks like a single Apache CouchDB instance. With clustering you could get 1) better performance, by having nodes process requests in parallel, and 2) reliability by having 2 extra document copies on separate nodes. If one or two node go down, you can still access you data. However there is more setup involved, with some firewall rules. See https://docs.couchdb.org/en/stable/cluster/index.html for more info. Clustering works best on reliable, low latency, network connections. Replication is a way to replicate data between any Apache CouchDB compatible endpoints. It's a peer-to-peer setup, which is kind of a unique feature amongst databases. All the data is replicated via the HTTP API interface. You can run replication jobs on any Apache CouchDB instance and it can replicate between any two other CouchDB instances. Replication can be bi-directional (A->B, B->A), or you can set up any other topology you like: a star, with a central instance, or a circle, etc. Replication is suitable even for high latency or unreliable networks, with intermittent connectivity. There are checkpoints and retries, which are all configurable. > Can I write to any node and it replicates to all the others with both methods or does that only work with one of them? In case of replications, you can achieve that with a bi-directional replication. If you have CouchDB instances A and B. You can replicate from A to B and then also from B to A. Those two replication jobs, then can also run on A, B, or even a third cluster C! You can read more about it in: https://docs.couchdb.org/en/stable/replication/index.html But you'd also have to be aware of conflicts since the same document could be updated concurrently on A and B.

Unrelated but feels like an ok opportunity to ask since it was mentioned--is there much of a difference between replication and the clustering?

Good find @rnewson
That patch hasn't been released yet I think. @catgirlinspace would you be
able to build Apache CouchDB `main` from source?
If you can, then you can try it out with this option:
```ini
[replicator]
ibrowse_options = [{prefer_ipv6, true}]
```

@nickva Not sure if that's the bug actually, as I'm getting this same error
when using internal domains from fly.io that have records. I'm able to
`curl` the same thing just fine, but CouchDB fails to replicate.
