The strength of a full-stack data engineer is the ability to bring the entire stack together, coordinating all of your microservices and features into a single product. Any developer can slap a new feature onto your project, but if new features aren't seamlessly integrated into your project as a whole, they will run inefficiently and slow down future development. See how everything can work together, from data pipeline to web app to data visualization and user-facing search functionality. View on Github
Cassandra DB performs writes fast and leaves read-heavy work to 3rd-party integrations. For example, Elassandra solves this with Elasticsearch and Datastax solves this with Solr and Spark (or even Graph depending on the use case). Of course, we could also integrate Cassandra with these same tools using open source connectors and drivers. Check out an example of how to extract your Cassandra into Spark for an ETL pipeline.
