kubegres VS cockroach

A good comparison with other operators here [2022]: https://blog.palark.com/cloudnativepg-and-other-kubernetes-o...

Personally I've only used Kubegres (https://www.kubegres.io/), which didn't even make the above list. It's ok for a personal project.

All k8s solutions for postgres take subtly different approaches. It seems that they've all converged on the Operator pattern. The basics are easy: run a database process which persists data to a cloud disk of your choice. The hard parts are how to update, migrate, backup, restore, monitor, failover, replicate, etc. These kubernetes "operators" promise to fulfill the role of a DBA but, just like hiring a DBA, it requires buy-in to their approach.

Reactive-Tech / Kubegres (opérateur)

I like https://www.kubegres.io, it takes a little getting used to how it works. I probably wouldn't use it for a huge database, but for things under a few TB it works great.

I don't know if you're using Kubernetes, but Kubegres is great for self hosting postgres on a cluster.

Any experience with https://www.kubegres.io/ ?

How does this compare with something like kubegres?

https://www.kubegres.io/

https://www.kubegres.io/ has worked well for me. You can use custom images, provided they follow the conventions of the official postgres image. I haven't tried a major-version upgrade yet - my impression is that it will probably be a bit painful and involve some downtime and manual ops.

Some of the more advanced operators might better handle the upgrade problem? But in general, I've been happy with Kubegres for a ~10GB database with low traffic.

There are some great operators out there that make deployment and management easy. I use kubegres managed with pgadmin and it has been working well for me.

CockroachDB is an open source distributed SQL database designed for scalability and resilience. While it offers SQL databases, CockroachDB is also compatible with PostgreSQL.

cockroachdb might be close: https://github.com/cockroachdb/cockroach

CockroachDB - SQL

For example, when you create a serverless postgres database with a platform like CockroachDB or Neon, you effectively get a connection string with a strong password. Anyone can connect to your database from anywhere so long as they have the right connection string. There are no security settings in these services to change this behavior.

I can also download VirtualBox and run all Windows programs, that would mean that all Windows apps are Linux apps?

> Yes you can for the most part

You can't statically link glibc: https://github.com/cockroachdb/cockroach/issues/3392

glibc can break stuff: https://www.gamingonlinux.com/2022/08/valve-dev-understandab...

I had binaries break because the newer version if openssl was put under a slightly different name.

Also, worth noting, if you're already using PostgreSQL (or plan to) you might want to take a look at https://www.cockroachlabs.com/ they have a free tier too and CockroachDB has a PostgreSQL interface.

I know that some projects like cockroach use custom build tools like bazel. But we actually really like to use to be able to build our projects simply with the great go toolchain and don't really aim to dive deep into custom build solutions.

CockroachDB is designed to be globally distributed. It has to handle causality when resolving collisions. It has to account for having a write operation to arrive after another and still have time priority because it was sent out a few milliseconds earlier.

Cockroachdb created a go runtime patch which measures the Grunning time of a goroutine: https://github.com/cockroachdb/cockroach/pull/82356. It doesn't entirely solve the problem though.

Our entire backend is written in Go. We've built a platform that allows other companies to offer automatic data syncing to their customers' data warehouses. Go works great for building distributed systems like this (see K8s). We're not the only ones in the space building data intensive applications with Go. Pachyderm, Pinecone, Cockroach Labs and are all also doing it. We've been quite happy with how Go has worked for us.
