GalacticChunks

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.

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 :)

fixed bug where it didnt save and some optimziations.

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.

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.
