: Ask clarifying questions. Define the scale (DAU, QPS), features, and constraints.

Use the GitHub notes you find to create a summary of key technologies: When to use Cassandra vs. DynamoDB? When to use Kafka vs. RabbitMQ? How to apply consistent hashing in various scenarios? Conclusion

(API endpoints, basic architecture blueprint). It is the art of finding a solution
