How Rust Powers High-Throughput Solana Swap Data Ingestion on a 4-CPU Pod

A technical deep-dive published on DEV Community outlines how to build a production-grade Solana transaction ingestion engine using Rust. The system tracks real-time swap activity across decentralized exchanges like Raydium, Orca, and Jupiter by maintaining persistent WebSocket connections to Helius RPC nodes instead of relying on traditional REST polling. To handle connection failures, the service uses an asynchronous reconnection loop with exponential backoff, automatically recovering from dropped sockets without manual intervention or data loss. Memory overhead is minimized by filtering out irrelevant transactions at the RPC layer and using zero-copy decoding via the Carbon crate, which converts raw byte arrays directly into typed Rust structures. The architecture is designed to sustain thousands of transactions per second on cost-effective infrastructure while decoupling ingestion from the database through a NATS message broker.
