VedDB Server v0.1.21 - First Stable Release 🎉

[Mihir-Rabari]

We're excited to announce the first stable release of VedDB Server! This marks a major milestone in the project, delivering a production-ready, high-performance in-memory key-value database server.

VedDB Server v0.1.21 is a fast, lightweight, and reliable database built in Rust, designed for low-latency data access with a simple TCP protocol.

✨ Core Features

• Fast KV Operations - Sub-millisecond SET, GET, DELETE operations
• LIST Command (opcode 0x09) - Enumerate all stored keys
• TCP Protocol - Simple, efficient binary protocol for network access
• Lock-Free Storage - Thread-safe KV store using DashMap for maximum concurrency
• Multi-Threading - Worker pool for concurrent request processing
• Session Management - Multi-client support with automatic cleanup
• Comprehensive Logging - Detailed server-side logging with tracing

🏗️ Architecture

• SimpleKvStore - Lock-free concurrent access with DashMap
• Worker Pool - 4 worker threads by default (configurable)
• Binary Protocol - Little-endian encoding, 24-byte command header, 20-byte response header
• Status Codes - Clear error handling (0x00=OK, 0x01=NotFound, 0x04=InternalError)

🚀 Performance

• Latency: < 1ms for most operations
• Throughput: 10,000+ ops/sec per connection
• Concurrency: Lock-free data structure for parallel access
• Memory: Efficient in-memory storage

📊 Technical Details

• Protocol uses consistent little-endian encoding
• Response header: 20 bytes (status:1, flags:1, reserved:2, seq:4, payload_len:4, extra:8)
• Command header: 24 bytes (opcode:1, flags:1, reserved:2, seq:4, key_len:4, val_len:4, extra:8)
• All operations are sub-millisecond latency

🎯 Supported Operations

OpCode	Command	Description
0x01	PING	Health check
0x02	SET	Store key-value pair
0x03	GET	Retrieve value by key
0x04	DELETE	Remove key
0x09	LIST	List all keys
