🎬 The Epic Journey: From 187K to 417 MILLION Events/Sec

Welcome to the most entertaining performance benchmark you'll ever see! This repository chronicles an epic battle between Rust, TypeScript, C, and Zig, where we pushed all languages to their absolute limits and beyond.

Spoiler Alert: Zig achieved 417 MILLION events/sec and is the new champion! ⚡👑

📖 The Story So Far...

What started as a simple streaming JSON pipeline benchmark turned into an optimization arms race that would make Formula 1 engineers jealous.

Overview

The benchmark evaluates a streaming JSON pipeline that processes events through four stages:

1. JSON Stream Ingestion: Receives batches of JSON events
2. Decode/Validation: Parses and validates incoming JSON
3. Transform/Enrich: Processes and enriches events
4. Index/Aggregate: Builds inverted indices and computes windowed aggregations

Architecture

Rust Implementation

• Runtime: Tokio async runtime with crossbeam channels
• Parallelism: Rayon for CPU-intensive operations
• Data Structures: AHashMap for fast lookups, HyperLogLog for distinct counting
• Memory Management: Efficient memory usage with smallvec and parking_lot

TypeScript Implementation

• Runtime: Node.js with worker threads for parallel processing
• Framework: Effect for functional programming and error handling
• Data Structures: Maps and Sets for collections, MurmurHash for consistent hashing
• Concurrency: Worker threads for parallel event processing

Features

Core Components

• Event Generator: Produces synthetic events with configurable distributions
• Inverted Index: Compressed postings for efficient term-based queries
• Windowed Aggregator: HyperLogLog-based distinct counting and top-k aggregation
• Backpressure Control: Configurable batch sizes and window parameters

Performance Metrics

• Throughput: Events processed per second
• Memory Usage: Peak memory consumption during processing
• Latency: Processing latency for different pipeline stages
• Scalability: Performance with varying worker/thread counts

Quick Start

Prerequisites
