Solving client problems through efficient Kafka Integration
The client, Companjon, faced a significant challenge in handling requests from business partners using the third-party product Graphene via Azure API Gateway. The requirement was to forward a copy of each request, both inbound and outbound, to a Kafka messaging system without impacting performance or response time. Additionally, these messages needed to be streamed to Databricks for further processing and analytics. Our architectural solution e8ectively addressed these needs through a robust, scalable, and flexible integration strategy.
To ensure seamless integration, we configured custom inbound and outbound rules (send-one-way) within the Azure API Gateway. This setup allowed us to forward a copy of each request to Kafka before sending it to Graphene. By employing an asynchronous, non-blocking mechanism, we ensured that the primary request processing remained unaffected, maintaining high performance and response times.
We deployed a Kafka cluster with horizontal scaling capabilities to manage high throughput and large volumes of requests. Extensive performance testing validated the cluster’s ability to handle millions of requests efficiently, ensuring consistent system response times and throughput.
To accommodate different data serialization needs, we developed two variants of Kafka producers using Spring Boot: one for Avro schema-based serialization and another for JSON schema-based serialization. These producers featured configuration management to switch seamlessly between Avro and JSON schemas based on client requirements.
Our solution included enhancing the Kafka producer to dynamically create topics if they did not already exist, ensuring scalability. We integrated an Avro schema registry for dynamic schema creation and encryption, providing secure and efficient data handling. The Kafka producer was designed to be highly configurable, meeting diverse client needs and ensuring adaptability for future requirements.
We developed a Kafka consumer using Python, implementing continuous streaming to pull messages from Kafka topics efficiently. Comprehensive error handling ensured robustness against connectivity issues, message parsing errors, and Kafka cluster downtime.
For Databricks integration, we configured the environment with necessary libraries to run the Kafka consumer. The consumer parsed incoming messages in both Avro and JSON formats and stored them in a bronze table within Databricks for raw data capture.
To ensure continuous data ingestion and processing, Databricks notebooks were scheduled to run at regular intervals. We automated the data transformation pipeline using Databricks Jobs, allowing timely updates from bronze to silver to gold tables. Monitoring tools were set up to track data ingestion rates, processing times, and resource usage, with alerts configured for quick response to any issues.
Our architectural approach successfully addressed Companjon’s requirements by implementing a robust Kafka integration solution. Leveraging scalable Kafka infrastructure, flexible Spring Boot-based producers, and seamless integration with Databricks, we ensured high performance, scalability, and data integrity. This solution not only met immediate needs but also provided a flexible and adaptable architecture for future enhancements, demonstrating our ability to deliver comprehensive and effective integration solutions.
