+# BLS RCU Action Server
+
+## Overview
+Backend service for processing RCU action events from Kafka, parsing them, and storing them in PostgreSQL. Includes error handling via Redis and heartbeat monitoring.
+
+## Architecture
+- **Input**: Kafka Topic (`blwlog4Nodejs-rcu-action-topic` or configured via env)
+- **Processing**: Node.js Service
+  - **Consumer**: `kafka-node` consumer group
+  - **Parser**: Parses JSON messages, handles UDP raw data decoding
+  - **Database**: PostgreSQL (Batch insert)
+  - **Error Handling**: Redis List (`error_queue`) for failed messages + Retry mechanism
+- **Output**: PostgreSQL Table (`rcu_action_events`)
+
+## Configuration (Environment Variables)
+The project is configured via `.env`. Key variables:
+- **Kafka**: `KAFKA_BROKERS`, `KAFKA_TOPIC`, `KAFKA_SASL_USERNAME`, `KAFKA_SASL_PASSWORD`
+- **Database**: `DB_HOST`, `DB_PORT`, `DB_USER`, `DB_PASSWORD`, `DB_DATABASE`, `DB_SSL`
+- **Redis**: `REDIS_HOST`, `REDIS_PORT`, `REDIS_PASSWORD`
+
+## Development Constraints
+- **Schema**: Must strictly follow `docs/readme.md`.
+- **Database**: Do not alter Schema Name (`rcu_action`) or Table Name (`rcu_action_events`) unless explicitly requested.
