1. Modify scripts inside the helpers folder:

• cubes_to_db: automate the process of ingesting cubes & their embeddings into the database by using the tables.json file
• drilldowns_to_db: automate the ingestion of drilldowns with the tesseract schema json

2. Create a pipeline to run everything together

3. New cubes, how to handle these?
