Configuration

Client configuration holds the necessary information for connecting to the Optimus server as well as for specification creation. Optimus provides a way for you to initialize the client configuration by using the init command. Go to the directory where you want to have your Optimus specifications. Run the below command and answer the prompt questions:

$ optimus init

? What is the Optimus service host? localhost:9100
? What is the Optimus project name? sample_project
? What is the namespace name? sample_namespace
? What is the type of data store for this namespace? bigquery
? Do you want to add another namespace? No
Client config is initialized successfully

After running the init command, the Optimus client config will be configured. Along with it, the directories for the chosen namespaces, including the sub-directories for jobs and resources will be created with the following structure:

sample_project
├── sample_namespace
│   └── jobs
│   └── resources
└── optimus.yaml

Below is the client configuration that has been generated:

version: 1
log:
  level: INFO
  format: ""
host: localhost:9100
project:
  name: sample_project
  config: {}
namespaces:
- name: sample_namespace
  config: {}
  job:
    path: sample_namespace/jobs
  datastore:
    - type: bigquery
      path: sample_namespace/resources
      backup: {}

Configuration	Description
Version	Supports only version 1 at the moment.
Log	Logging level & format configuration
Host	Optimus server host
Project	Chosen Optimus project name and configurations.
Namespaces	Namespaces that are owned by the project.

Project

• Project name should be unique.
• Several configs are mandatory for job compilation and deployment use case:
  • storage_path config to store the job compilation result. A path can be anything, for example, a local directory path or a Google Cloud Storage path.
  • scheduler_host being used for job execution and sensors.
  • Specific secrets might be needed for the above configs. Take a look at the detail here.
• You can put any other project configurations which can be used in job specifications.

Namespaces

• Name should be unique in the project.
• You can put any namespace configurations which can be used in specifications.
• Job path needs to be properly set so Optimus CLI will able to find all of your job specifications to be processed.
• For datastore, currently Optimus only accepts bigquery datastore type and you need to set the specification path for this. Also, there is an optional backup config map. Take a look at the backup guide section here to understand more about this.
