cass-operator VS golang-docker

Alright! So does this Cassandra operator fullfil does demands? https://github.com/k8ssandra/cass-operator

cass-operator

We can illustrate the above concept by creating a lightweight overlay network for Cassandra’s internode traffic. We’ll deploy a Cassandra cluster consisting of two datacenters using the open source cass-operator. After preparing two Kubernetes clusters of 3 nodes each (2 CPU & 4 GB RAM), perform the following steps. Steps one through five are performed in both kubes, while steps six and seven are different for each:

The next step is to create the cluster. The following deployment file creates a 3 node cluster. It is largely a copy from the upstream cass-operator version 1.7.0 file example-cassdc-minimal.yaml but with a small modification made to allow all the pods to be deployed to the same worker node (as CodeReady Containers only uses one k8s node by default).

I have customers that are using DSE on Kubernetes in production right now with cass-operator. Regarding choosing one product over the other, I think you want to look at the features your application needs and make the choice there. DSE has a number of features that are not present in K8ssandra. I would not be surprised to see users running a mix of both depending on their needs.

Golang: Download and install Golang from the official website.

After installing the Docker Desktop, you need to have Golangand Cobra cli installed before building the CLI.

Visit the official Go website at golang.org and download the latest version for your OS.

With Go it is a bit different. We do not have exceptions, but we have panic and recover functions. Panics by themself are not control-flow statements, they are closer to Java Error type or PHP ErrorException type. They are used to stop execution of the program in case of critical errors that are not related to business flow of the program. In case of Go we can use panic to throw an error and recover to catch it, but we can catch it only in defer functions that are not linear execution code block and applies some limitations on top of it.

Before diving into Go programming, you need to set up the development environment. Go's official website (https://golang.org) provides installation binaries for all major operating systems. Once installed, you can confirm the installation by running a simple "Hello, World!" program.

Next, you need to install Golang, which is the programming language used for the accompanying Golang application. Visit the official Golang website at https://golang.org and follow the installation instructions specific to your operating system. Once installed, make sure the go command is accessible from the command line by adding the appropriate binary directory to your system's PATH.

To start in Go❤️ let's take a few steps back, let's start our whole trajectory knowing the official website of lang this is the official page golang.org, here we will find all the information we could know about Go and much more. Here we have the docs, packages, blog and our darling play.golang.org, language specs, download, Go tour and much more.
