Functional Requirements

1. users send prompts -> get video some time later

2. users can choose length, quality

3. users can poll for status of video generation

4. scale: XXM DAU

Non-functional Reqs.

1. workflow progress should be persisted to protect against failures

2. aim to not so high latency

3. availability >> consistency, since users will want to continue using service as much as possible

4. system should be fair for each tenant (not favors some tenants)

5. output safe (needs to run several safety checks before returning to user)

6. should be efficient to minimize costs

Capacity Estimation

Estimate the scale of the system. Consider daily active users, read/write ratio, storage requirements, bandwidth, and any relevant QPS calculations...

Entities:

1. Users: id (pk), name, email, info

2. Request: id (pk), orig_user (fk), timestamp, prompt, length, quality, status, rw_prompt

API:

REST for users

POST /requests/ -> request_id, status

@user JWT

Request {

description,

length,

quality

}

GET /requests/{id} -> request status, and video info

@users JWT

-> vide_info: {list of BLOB storage URLs to download video chunks}

Database Design

Define the data model. Identify the main entities, their attributes, and relationships. Consider the choice of database type (SQL vs NoSQL) and justify your decision based on access patterns...

Detailed Component Design

Deep dive into 2-3 key components. Explain how they work, how they scale, discuss tradeoffs, capacity, and any relevant algorithms or data structures.
