Best-rated movies example - Redpanda version

In this project, you build an end-to-end application with Pathway to compute the K-best-rated items in a movie dataset.

The project is organized as followed:

• a streaming platform: Redpanda
• a Python container creating the stream from a static CSV file and sending it to Redpanda
• a Python container computing the K-best-rated items using Pathway

The different containers are managed via docker-compose.

A toy dataset is provided in the sources, formatted in the same way as the MovieLens25M dataset: we encourage you to test it on the entire dataset.

Launching the program

You can launch the project using docker compose up -d or using the make file.

To access the Pathway's container and check the results:

• connect to the container with make connect (or docker compose exec -it pathway bash)
• print the file cat best_ratings.csv

You can access the logs of the different containers using the commands in the Makefile
