COPY . .
RUN npm ci
CMD npm startdocker ps -a shows Exited (0). The app is a long-running server. What am I missing?

Lakehouse for the silver layer if you want Spark notebooks and Delta; Warehouse if your team is SQL-first. Pipelines orchestrate, notebooks transform. Keep bronze as raw files, silver as cleaned Delta tables, gold as a star schema.

Yes, use a bridge table. Create a distinct dimension with unique keys, relate both fact tables to it as many-to-one, and hide the raw many-to-many. DAX measures stay simple and USERELATIONSHIP becomes unnecessary.

Your CMD npm start runs in a shell that exits. Also you're missing EXPOSE and a proper working directory. Try:
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
CMD ["node", "server.js"]Exec form (["node", ...]) keeps the process as PID 1.
