How to launch

docker-compose build
docker-compose up

This page will be updated with websockets http://127.0.0.1:8085/

Swaps will start generating after 10 seconds - this pause is required to wait for Postgres to come online.

Most knobs are configurable - see cmd flags.

To whom it may concern

Three main components:

cmd/producer - continuously generates random swaps and persists them in PG. By default, generates 1000 swaps per second.
cmd/swapper-api - serves index.html (/), websocket API (/ws) and JSON api (/stats).
cmd/swapper-worker - processes new swaps and pushes them into VM (VictoriaMetrics).
All stats are calculated with VM.
Swaps are durably stored in PG.
Producer assigns each swap an ULID, which is used as primary key in Postgres, and it's timestamp part is used for VM.
Swaps are transported to VM with the outbox pattern.
Due to VM apparently not supporting idempotency, swaps could be inserted into VM multiple times, in case of network issues.
