Note that while GalacticChunks is still in development, each version gets tested to see if it works so play without worry. Made by Musawer

GalacticChunks is a next‑generation chunk storage engine that replaces Minecraft’s bulky .mca region files with a sleek, highly‑compressed .gregion format. It’s built for servers that want cleaner world storage, faster disk operations, and long‑term reliability—without touching Paper’s chunk logic or interfering with gameplay.

GalacticChunks is purely a storage layer. It does not modify world generation, ticking, lighting, or Paper/Purpur internals. Your server plays exactly the same—your world just becomes dramatically more efficient behind the scenes.

🚀 Key Features • Safe, Automatic Migration from .mca → .gregion GalacticChunks includes a fully safe migration system that converts your existing vanilla region files into its optimized .gregion format.

No commands

No world resets

No data loss

No interruptions

Your world stays exactly the same—only the storage format changes.

⭐ Your world is NEVER deleted Installing GalacticChunks does not wipe, reset, or regenerate your world. It simply reads your existing .mca files and writes them into .gregion format. If you ever remove the plugin, your original .mca files remain untouched.

⚡ 3× to 10× Smaller Region Files .gregion files are designed to be 3–10× smaller than vanilla .mca, using a combination of:

modern compression (including Zstd)

tighter binary layouts

reduced overhead and redundancy

This means:

faster backups

faster uploads/downloads

less disk I/O under load

significantly lower storage usage on hosts

🧪 Modern Compression Stack, Pure Java GalacticChunks uses a stack of modern compression and encoding techniques, including Zstd, to balance:

high compression ratio

fast decompression

stable performance

full cross‑platform support

Everything runs in pure Java—no native libraries, no JNI, no OS‑specific hacks.

🛠 Pure Storage Layer — Zero Gameplay Interference GalacticChunks does not change how chunks behave in‑game. It only changes how they are stored on disk.

It works seamlessly alongside:

ViaVersion / ViaBackwards / ViaRewind

ProtocolLib

AuthMe

Essentials

Anti‑Xray

Any world generator

Any Paper/Purpur fork

If your server loads chunks, GalacticChunks stores them—nothing more.

🌠 Perfect For Long‑term SMPs

Large or old worlds

Servers with limited disk space

Hosts with slower or shared storage

Anyone who wants cleaner, safer world files

4.0.0Релиз1.21.9, 1.21.10, 1.21.11 · 9 января 2026 г.

GalacticChunks 4.0 is no longer a custom chunk-loading system. It has evolved into a pure storage-layer optimization. We’ve removed the complexity of custom chunk handling and now hook directly into Paper’s native system. The result? The same 3–10× compression you love, with zero compatibility risks. 🛠️ The 4.0 Evolution: Pure Storage In 4.0, we’ve stripped the plugin down to its most powerful core. Paper-Native: We no longer load or unload chunks ourselves. Paper handles the logic; we just handle the storage. Plug-and-Play: Because we inject directly into Paper’s chunk system, GalacticChunks is now compatible with every world-gen and utility plugin on the market. Simplified .gregion v1: We’ve moved to a clean, dictionary-free format. This eliminates the misalignment and OOM (Out of Memory) crashes that plague other compression methods. 🚀 Performance & Stability Highlights 📦 3–10× Smaller Worlds: Massive storage savings using 100% pure ZSTD compression. ⚡ Rock-Solid Async Saving: We’ve eliminated the "Failed to save chunk: null" errors by rebuilding the AsyncChunkSaver loop from scratch. 🧠 Zero-Impact Migration: Our new MigrationManager is TPS-aware. If your server starts lagging, the migration pauses automatically. 💾 No More Disk I/O Bottlenecks: Smaller files and optimized ChunkFile readers mean your SSD spends 50–90% less time working. 🛡️ Why You Can Trust 4.0 Non-Destructive: Chunks are read from your vanilla .mca files. We never delete your original data until the new .gregion file is verified. Resume-Ready: Migration tracks progress and resumes automatically after a restart. Clean Slate: This is a complete rewrite. We fixed the leaks, fixed the crashes, and fixed the "OOM" issues of the past. ⚠️ How to Upgrade Delete any old .gregion files from version 3.x (they are incompatible with the new v1 format). Install GalacticChunks 4.0.0.0. Relax: The plugin will automatically and safely remigrate your world from the vanilla .mca files. Your progress is 100% safe.

3.0.0Релиз1.21.9, 1.21.10, 1.21.11 · 30 декабря 2025 г.

completely rewrote binary storage system, HEAVILY MORE OPTIMZED ,improved code so eaiser to understand , i decided that instead of limiting v3 of GalacticChunks so it works with the earlier version it redoes the entire storage system for way more optization , new optimzedsections made it so air gets like undefined and that helps performance by alot cuz instead of naming each air blocks it just doesnt get caled then it like aded laterwhich helps alot and code is way more stable now :)

2.3.1Релиз1.21.9, 1.21.10, 1.21.11 · 29 декабря 2025 г.

fixed bug where it didnt save and some optimziations.

2.3.0Релиз1.21.9, 1.21.10, 1.21.11 · 29 декабря 2025 г.

made it so instead of just deleting all .mca files it instead migrates them to the .gregion files then deletes so when server owners transfer they dont lose progress. also added some stuff to the config and its easier to debug now.

2.2.0Релиз1.21.9, 1.21.10, 1.21.11 · 29 декабря 2025 г.

Dirty‑chunk tracking system that detects when a chunk actually changed (block place/break, pistons, explosions, etc).

Chunk saving now only happens for modified chunks instead of every unload.

New .gregion write‑safety improvements (flush on eviction, safer metadata writes).

Updated RegionFile with proper flushing, chunk counting, and cleaner dictionary handling.
