## Running

You'll need to install Docker and Docker compose to be able to spin up the DBs instances, after that run:

- docker-compose up -d

- npm ci

- npm run seed

- npm start

## Errors?

In case you got an error of too many processes open, try decreasing the const [CLUSTER_SIZE](https://github.com/ErickWendel/parallelizing-nodejs-ops/blob/main/src/index.js#L8C1-L8C24) variable
