cloudnative-pg VS percona-postgresql-operator

My holiday project was doing another pass at my Homelab Kubernetes cluster, part of which involved switching to a proper operator to manage Postgres. Coincidentally, I setup cloudnative-pg (https://github.com/cloudnative-pg/cloudnative-pg) yesterday.

Only the TPS

(How) Do any ~pg_top tools delineate logical replication activity?

We already had backup and recovery using object storage, but we are working to support VolumeSnapshots taking care to properly shut down the instance first! This awesome PR is laying the foundation for it, it's adding a subcommand to our kubectl plugin to manually perform a backup using VolumeSnapshots and adding support for restoring a Cluster from it, next step will be adding it to the ScheduledBackup/Backup resources too!

I'll ask in their slack channel later. I've also opened a discussion regarding this on github if you are interesed. https://github.com/cloudnative-pg/cloudnative-pg/discussions/2030

This has a bunch of side-effects that break usual expectations around scheduling. For instance, cluster scale-down (for maintenance etc.) is blocked unless a specific taint has been added to each database pod. In addition, if the underlying node does fail, your cluster will be stuck in fail-over state until you manually delete the underlying pods. I think there are definitely other gotchas around this decision to use a custom controller but I have only tested this on GKE.

Another option would be https://github.com/cloudnative-pg/cloudnative-pg I got to see this talk at Kubecon last month that might be of use to you too -> https://www.youtube.com/watch?v=99uSJXkKpeI That talk is run in part by EDB, who are the company behind CloudNativePG, they are talking about their commercial offering, but the principle is the same.

Following another post on this sub, I was checking out the Github project and landed on this 2864 lined CRD https://github.com/cloudnative-pg/cloudnative-pg/blob/main/config/crd/bases/postgresql.cnpg.io_clusters.yaml. How are sane people reading these files?

**NOTE**: I am a maintainer of CloudNativePG.

I have made very good experiences with operators from percona. Feel free to try it https://github.com/percona/percona-postgresql-operator

CEO Percona Here.

It is more than "Percona Thinks" We have number of customers who started using Crunchy Kubernetes Operator based solution thinking it is Open Source and were contacted by Crunchy Sales team to indicate they need subscription to use it.

This was one of the reasons for them to move to Percona Operator for PostgreSQL which does not require any commercial relationship with Percona to use in practice and completely Open Source
