kuhl-haus-mdp-servers
Container image build repository for market data platform data plane servers.
Overview
This package provides the server entry points and Docker container images for the Kuhl Haus Market Data Platform (MDP) data plane. Each server wraps components from the kuhl-haus-mdp library and runs as an independently scalable container in Kubernetes.
Servers
- Market Data Listener (MDL)
WebSocket client connecting to Massive.com, routing events to RabbitMQ queues with minimal processing overhead.
- Market Data Processor (MDP)
Horizontally-scalable event processor with semaphore-based concurrency, delegating to pluggable analyzers and writing results to Redis cache.
- Leaderboard Analyzer (LBA)
Redis pub/sub consumer running leaderboard and trade analyzers with sequential message processing.
- Widget Data Service (WDS)
FastAPI/WebSocket-to-Redis bridge providing real-time streaming to client applications with fan-out pattern.
- Finlight Data Listener (FDL)
WebSocket client connecting to Finlight, subscribing to real-time financial news feeds and publishing enriched articles to RabbitMQ queues.
- Finlight Data Processor (FDP)
RabbitMQ consumer processing enriched news articles from the FDL queue, running FinlightDataAnalyzer to cache articles in Redis and publish updates to downstream consumers.
Each server has a standard Dockerfile and an OpenTelemetry-instrumented variant (*_otel.Dockerfile) for production observability.

Code Organization
The platform consists of four main packages:
Market data processing library (kuhl-haus-mdp) - Core library with shared data processing logic
Backend Services (kuhl-haus-mdp-servers) - Market data listener, processor, and widget service
Frontend Application (kuhl-haus-mdp-app) - Web-based user interface and API
Deployment Automation (kuhl-haus-mdp-deployment) - Docker Compose, Ansible playbooks and Kubernetes manifests for environment provisioning
Configuration
All servers are configured via environment variables. See the Configuration Reference for the full list of variables per server, including defaults and descriptions.
Documentation
