Uploading and download Minecraft worlds from mysql

The idea was to be able to upload worlds to a database so that we could have multiple servers upload and download them at will to enable load balancing for servers such as skyblock as the demands of scalable 1.17 servers grow while the performance falls version to version.

The important idea here was to see if it was possible to upload worlds to a database, which the answer is yes :D. but this even works better for skyblock servers as they are mostly air, which allowed us to do a small optimization. which is when a chunk is empty, we don't have it, as generating empty chunks is cheap as chips, but storing them has about 500B of overhead. so it ends up taking longer to fetch them from the database, then just generate them.

# This file describes the standard way to build Docker, using docker
#
# Usage:
#
# # Assemble the full dev environment. This is slow the first time.
# docker build -t docker .
#
# # Mount your source in an interactive container for quick testing:
# docker run -v `pwd`:/go/src/github.com/docker/docker --privileged -i -t docker bash

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
