Relativistic Documentation

Relativistic is the fastest way to get a compliant data stack based on open source tools up and running, both locally and on cloud providers, saving hundreds of thousands of dollars in vendor costs.

Relativistic configures open source data tools on a Kubernetes cluster via Terraform. It allows you to deploy over a dozen of the most popular data tools on Kubernetes in under 5 minutes. From dashboarding to ETLs to DAG schedulers to metrics and more, Relativistic has you covered.

Many open source data tools are better than their closed source counterparts. The issue is deploying them in a way that is secure, scalable, maintainable, and compliant. Relativistic comes from the learnings of a data consultancy deploying the same tools to dozens of clients, and how to get running in a day.

Demo

Example - Set up Superset

Prerequisites:

main.tf

provider "kubernetes" {
  config_path = "~/.kube/config"
}

provider "helm" {
  kubernetes {
    config_path = "~/.kube/config"
  }
}

module "relativistic" {
    source = "kadreio/relativistic/kubernetes"
    superset_enabled = true
    superset_default_password = "starting_password_to_change"
    superset_default_user = "[email protected]"
    superset_secret_key = random_string.cookie_key.result
}

resource "random_string" "cookie_key" {
    length  = 32
    special = false
}

command

$ terraform init
$ terraform apply --auto-approve
$ open http://localhost:30086
