Write Performance Benchmark

This document will allow anyone to verify the benchmark result of writing 2 - 3 million metrics per second into DalmatinerDB. This is a single node benchmark to keep things simple and easily comparable between time series databases that don't support clustering.

We will setup 2 Haggar servers to generate metrics and fire them at a single node DalmatinerDB server as per this diagram.

You can expect near linear performance results as a DalmatinerDB cluster is horizontally scaled.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
