Orchestrate MongoDB operations with Apache Airflow

This repository contains the example DAG described in the Orchestrate MongoDB operations with Apache Airflow tutorial. It ingest descriptions of video games from a local text file, creates vector embeddings using OpenAI and then loads the embedded data into a MongoDB collection. Additionally the DAG will set up the collection and search index if they do not already exist. The DAG also contains a task to query the data for specific concepts.

Content

This repository contains:

  • query_game_vectors: A DAG showing how to ingest text data as vector embeddings into MongoDB and query the data.
  • test_conn: A DAG to test the connection to MongoDB.

How to run the demo

  1. Fork and clone this repository.
  2. Make sure you have the Astro CLI installed and that Docker is running.
  3. Copy the .env.example file to a new file called .env and fill in your own values and credentials into the <> placeholders. You will need a running MongoDB cluster as well as an OpenAI API key of at least tier 1.
  4. Run astro dev start to start the Airflow instance. The webserver with the Airflow UI will be available at localhost:8080. Log in with the credentials admin:admin.
  5. Run the test_conn DAG to test your connection to MongoDB.
  6. Run the query_game_vectors DAG to ingest text data as vector embeddings into MongoDB and query the data. When running the DAG you can provide concepts to query the data for.
