Introductory sample scala app using Apache Spark Streaming to accept data from Kafka and write a summary to Cassandra.

sample Spark Cassandra with SSL

This project provides a reference implementation for running Apache Spark analytics on Cassandra databases with SSL/TLS encryption. It serves as a practical example for developers needing to process data securely in distributed environments where encryption is required for compliance or security. ## Key Features - **SSL/TLS Encryption** — Demonstrates secure connection configuration between Spark and Cassandra using SSL certificates - **Spark-Cassandra Integration** — Shows how to use the Spark Cassandra connector for data processing workflows - **Sample Analytics Job** — Provides a working example that can be adapted for production use cases - **Build and Deployment Guidance** — Includes instructions for compiling and submitting the job to Spark clusters ## Philosophy This sample project follows a practical, example-driven approach to help developers quickly implement secure data processing pipelines without starting from scratch.
