009: Secret Agent Usage

Inspiration

• Working in Rust
• Working on usage, a growing part of the subscription industry

What it does

• Collects raw usage from the customer
• Aggregates usage data and sends it to billy

How we built it

• We built it in Rust, using Jelly as a starter, sqlx and postgres for storage, and HTTP for the API
• We also wrote a script in python for testing

Challenges we ran into

• Rust is confusing
• Did not have time to fully implement the billy side of things
• Performance is still a bit slower than we would like it to be

Accomplishments that we're proud of

• We built it!
• We are more confident in rust now
• We actually implemented aggregation on the agent

What we learned

• How to write good rust
• The limits of performance

What's next for 009: Secret Agent Usage

• Improve performance. Switch to sqllite or other fast DB
• run jobs based on configured timer instead of being called manually
• Implement billy acceptance of aggregated data

Built With
