Database 2

Database 2 is a new modern nosql, file path based database.

It needs the same amount of ram for datas ranging from 1mb to 1e+75TB, no ram difference for data!

This package contains 2 separate classes Client and Server

Performance Server

This is the ClustedServer function inside the package. It creates multiple server instances but costs a lot of resources

const {ClustedServer} = require("database-2.js");

ClustedServer(instances, port, users, callback fn)

Instances

Number of instances to run (for eg. 800, min 1)

WARNING

Costs a lot of resources

port & users & callback fn

See constructor props

Server

The server is the backend of the database wrapper. It should be always 24/7 running in order for database to work.
