Anaxi

Anaxi is Superhog's tool to perform Extract-Load (EL) syncs between our multiple Cosmos DB databases and our DWH.

How to use the tool

Note: the app has only been used so far in a Linux environment. Windows support is dubious.

Install

• Ensure you have Python 3.10>= and poetry installed.
• Run poetry install to install dependencies.
• Activate the project's virtual environment. You can use poetry shell.
• Test that everything is working by running anaxi smoke-test. You should see a happy pig.

Set up credentials

anaxi needs a few configs and secrets to run.

Regarding Cosmos DB databases: anaxi expects to find a file called cosmos-db.yml in the path ~/.anaxi/cosmos-db.yml. The file should specify one or more Cosmos DB databases, along with the required secrets to interact with them. You can check the example file in this repo named example-cosmos-db.yml to understand how to build this file. Once you've done that, you can check if any database is reachable with the cosmos-db-healthcheck command. See more in the General Usage section below.

General Usage

You can run a healthcheck against any Cosmos DB database like this:

anaxis cosmos-db-healthcheck --cosmos-db-id <your-db-id>

Incremental scopes

• Callable CLI app
• Env vars readable from file system
• Healthchecks against Cosmos DB doable
• Healthchecks against DWH doable
• Reading from Cosmos DB
• Writing into DWH
• Refactors and improvements

What's with the name

Anaxi is short for Anaximander. Anaximander of Miletus was a pre-Socratic Greek philosopher who lived in Miletus. He is often called the "Father of Cosmology" and founder of astronomy.
