High-Throughput Edge Pipeline: Technical Specification
Author: Distributed Systems Core Team
Status: Approved for Implementation
Version: 2.4.0
Target Delivery: Q4 Sprint 3
1. Executive Summary & Objectives
This document establishes the architecture for an edge message routing pipeline capable of processing 100,000 events/second per cluster. The system prioritizes deterministic sub-5ms latency and zero-copy deserialization in client-side WebAssembly runtimes.
2. System Architecture
The topology isolates ingress listeners from backpressure queues to eliminate packet starvation under peak load.
•Ingress Gateway: Non-blocking epoll sockets terminate TLS connections.
•Message Dispatcher: Ring-buffer partitioner calculates consistent murmur3 hashes.
•Worker Pools: WebAssembly SIMD kernels process payload transformations.
•Persistence Log: Local WAL buffer guarantees at-least-once delivery semantics.
3. Data Interface & Schema Contract
The wire protocol uses compact binary serialization with typed fallback structures:
json
{
"eventId": "evt_998412-a7b",
"partitionKey": "tenant_4401",
"timestamp": 1727481600000,
"payload": {
"action": "TRANSACTION_SETTLE",
"batchSize": 256,
"checksum": "0x7F4A8C01"
}
}4. Performance & Validation Metrics
