Dank Stocks Inc

Dank Stocks Inc is a toy day trading system, built as part of a higher year distributed systems class at school. It's essentially a REST API, written in Golang accompanied by postgres,redis, rabbitmq, and docker. The picture below was the final architecture for the system by the end of the term. It's not perfect, but we scaled it to about ~15k transactions per second, for a 1.2 million transaction test file.

The core business logic lives of transaction server lives here.

Things we could add

• Add local user cache
• Shard user database
• Convert REST structure to a completely asynchronous system. Expose an API, which issues requests as messages on rabbit, which gets picked up by a worker. Use websockets to send data back.
