MichaelThis isn't good, coming from cloud-native-pg:Warning: mismatch architecture between controller and instances. This is an unsupported configuration.Which is true, my cluster is a mix of ARM64 Pis and x86 VMs. But I can't find any info on why this configuration is unsupported.<a href="https://social.mei-home.net/tags/HomeLab" class="mention hashtag" rel="nofollow noopener" target="_blank">#HomeLab</a> <a href="https://social.mei-home.net/tags/CloudNativePG" class="mention hashtag" rel="nofollow noopener" target="_blank">#CloudNativePG</a>

MichaelUp to now, I just had one database cluster, with all my DBs in it, and no replication. That was backed up every night with a pg_dump piped into restic and pushed to my S3. Which was deduplicating, incremental and encrypted.On the other hand: Declarative creation of DBs. 😬 4/fin<a href="https://social.mei-home.net/tags/HomeLab" class="mention hashtag" rel="nofollow noopener" target="_blank">#HomeLab</a> <a href="https://social.mei-home.net/tags/k8s" class="mention hashtag" rel="nofollow noopener" target="_blank">#k8s</a> <a href="https://social.mei-home.net/tags/CloudNativePG" class="mention hashtag" rel="nofollow noopener" target="_blank">#CloudNativePG</a>

MichaelFinally, there's the backups. I spend the entirety of yesterday trying to understand those. And they do seem to be nice, especially with also supporting S3 backup targets.But they just seem complicated. There's seemingly a base backup of the PGDATA folder, and then there's a stream of WAL files. Both are needed for restoring the DB. And there's encryption, but it's based on the S3 impl, from what I understand, and I don't have that set up in my Ceph cluster.3/x<a href="https://social.mei-home.net/tags/HomeLab" class="mention hashtag" rel="nofollow noopener" target="_blank">#HomeLab</a> <a href="https://social.mei-home.net/tags/k8s" class="mention hashtag" rel="nofollow noopener" target="_blank">#k8s</a> <a href="https://social.mei-home.net/tags/CloudNativePG" class="mention hashtag" rel="nofollow noopener" target="_blank">#CloudNativePG</a>

MichaelSo how much CPU/memory does my Mastodon DB need, compared to something like Gitea? Next one is the question of disk space. With one multi-db cluster, I have one large disk and that's it. With many mini-clusters, I need to figure out how much space each needs. Then there's also the WAL I would need to take into account.2/x<a href="https://social.mei-home.net/tags/HomeLab" class="mention hashtag" rel="nofollow noopener" target="_blank">#HomeLab</a> <a href="https://social.mei-home.net/tags/k8s" class="mention hashtag" rel="nofollow noopener" target="_blank">#k8s</a> <a href="https://social.mei-home.net/tags/CloudNativePG" class="mention hashtag" rel="nofollow noopener" target="_blank">#CloudNativePG</a>

MichaelI think I'm starting to really bounce off cloud-native-pg. I really like the idea of creating databases in a declarative manner, instead of working through sequences of commands to create databases and users. But with cloud-native-pg, I can only declaratively create entire database clusters. This has a number of problems I don't have good answers to. It starts with "Okay, what kind of resource requests to do I put onto them?"1/x<a href="https://social.mei-home.net/tags/HomeLab" class="mention hashtag" rel="nofollow noopener" target="_blank">#HomeLab</a> <a href="https://social.mei-home.net/tags/k8s" class="mention hashtag" rel="nofollow noopener" target="_blank">#k8s</a> <a href="https://social.mei-home.net/tags/CloudNativePG" class="mention hashtag" rel="nofollow noopener" target="_blank">#CloudNativePG</a>
