Note that while GalacticChunks is still in development, each version gets tested to see if it works so play without worry. Made by Musawer<\/p>\n
GalacticChunks is a next\u2011generation chunk storage engine that replaces Minecraft\u2019s bulky .mca region files with a sleek, highly\u2011compressed .gregion format. It\u2019s built for servers that want cleaner world storage, faster disk operations, and long\u2011term reliability\u2014without touching Paper\u2019s chunk logic or interfering with gameplay.<\/p>\n
GalacticChunks is purely a storage layer.
\nIt does not modify world generation, ticking, lighting, or Paper\/Purpur internals.
\nYour server plays exactly the same\u2014your world just becomes dramatically more efficient behind the scenes.<\/p>\n

\u26a1 3\u00d7 to 10\u00d7 Smaller Region Files
\n.gregion files are designed to be 3\u201310\u00d7 smaller than vanilla .mca, using a combination of:<\/p>\n
modern compression (including Zstd)<\/p>\n
tighter binary layouts<\/p>\n
reduced overhead and redundancy<\/p>\n
This means:<\/p>\n
faster backups<\/p>\n
faster uploads\/downloads<\/p>\n
less disk I\/O under load<\/p>\n
significantly lower storage usage on hosts<\/p>\n
\ud83e\uddea Modern Compression Stack, Pure Java
\nGalacticChunks uses a stack of modern compression and encoding techniques, including Zstd, to balance:<\/p>\n
high compression ratio<\/p>\n
fast decompression<\/p>\n
stable performance<\/p>\n
full cross\u2011platform support<\/p>\n
Everything runs in pure Java\u2014no native libraries, no JNI, no OS\u2011specific hacks.<\/p>\n
\ud83d\udee0 Pure Storage Layer \u2014 Zero Gameplay Interference
\nGalacticChunks does not change how chunks behave in\u2011game. It only changes how they are stored on disk.<\/p>\n
It works seamlessly alongside:<\/p>\n
ViaVersion \/ ViaBackwards \/ ViaRewind<\/p>\n
ProtocolLib<\/p>\n
AuthMe<\/p>\n
Essentials<\/p>\n
Anti\u2011Xray<\/p>\n
Any world generator<\/p>\n
Any Paper\/Purpur fork<\/p>\n
If your server loads chunks, GalacticChunks stores them\u2014nothing more.<\/p>\n
\ud83c\udf20 Perfect For
\nLong\u2011term SMPs<\/p>\n
Large or old worlds<\/p>\n
Servers with limited disk space<\/p>\n
Hosts with slower or shared storage<\/p>\n
Anyone who wants cleaner, safer world files<\/p>\n","protected":false},"excerpt":{"rendered":"
