🌌 Tachyon v2.0.0-beta.1 — Next-Gen Distributed Player Data Engine

We are thrilled to announce the first pre-release of Tachyon 2.0!
This major release is a complete re-architecture of Tachyon, moving away from legacy database models to a high-throughput, zero-loss reactive microservice powered by Quarkus 3.x, pure BSON gRPC streaming, Redis distributed locks, asynchronous DB batching, and MongoDB.

⚠️ Pre-Release Notice: This build is intended for testing and staging environments. Please report any issues or feedback on our GitHub Issues.

🚀 Key Highlights & What's New

⚡ Pure BSON & High-Throughput DB Batching

• Dynamic BSON Components: Stored as schema-free BSON documents preserving 100% NBT, ItemMeta, and custom component fidelity without schema migrations.
• RawBsonDocument Streaming: Direct binary BSON streaming over gRPC eliminates conversion overhead.
• Asynchronous DB Batching: Database writes (MongoDB & Redis Streams) are now processed in bulk batches (bulkWrite), drastically reducing I/O roundtrips and keeping DB latency minimal during traffic peaks.

🔒 Distributed Session & Anti-Dupe Locking

• Redis-backed atomic profile locks guarantee that player data is safely saved and loaded before server switches.
• Completely eliminates race conditions and inventory dupe glitches during cross-server hops.

⏪ Granular Snapshots & S3 Cold Archival

• Zero-CPU Compression: Removed application-level zstd compression from Spigot and Quarkus, delegating compression natively to MongoDB (WiredTiger).
• Automated S3 Archiver: Old snapshots are automatically purged from MongoDB and archived into AWS S3 / MinIO.

🛡️ Resilient Local Recovery Queue

• The Spigot plugin safely rejects new player logins if the backend is unreachable to protect state, while active player mutations are buffered locally and replayed with zero data loss upon reconnection.

📊 Observability, FastStats & Diagnostics

• FastStats & Micrometer (Spigot): Integrated FastStats and Micrometer on the Minecraft plugin with dedicated scrapers (TachyonMetrics, VanillaMetrics) to track TPS, JVM specs, memory pools, GC pauses, and internal queue sizes in real time with near-zero overhead.
• Richer gRPC Health-Checks: Revamped the gRPC health-check service (/ping) with detailed diagnostics, reporting live MongoDB/Redis connectivity, cached health states, and node status metrics.
• Upgraded Grafana Dashboards: Refreshed ready-to-use Grafana dashboards to visualize player sync latencies, database bulk throughput, stream queues, and FastStats metrics live.

⚙️ DevOps & DX Improvements

• Automatic Config Export: Generates config/application.yaml on first boot for seamless Docker and bare-metal editing.
• Standalone Uber-JAR: Added a dedicated Maven profile (-Puber-jar) to generate a single self-contained runnable JAR.

📦 Artifacts in this Release

🛠️ Quick Start

1. Start the Backend

java -jar tachyon-service-2.0.0-SNAPSHOT-runner.jar

(On first startup, a default config/application.yaml file will be automatically generated in your working directory for easy editing).

2. Install the Spigot Plugin

1. Drop tachyon-minecraft-plugin-2.0.0-SNAPSHOT.jar into your server's plugins/ folder.
2. Configure plugins/Tachyon/config.yml to point to your backend gRPC host & port.
3. Restart your server.
