Spark
Apache Spark is a unified distributed data processing engine designed for large-scale data analysis and computation graphs. It functions as a distributed machine learning framework, a graph processing system, a real-time stream processor, and a SQL analytics engine.
The system enables the execution of distributed SQL querying, large-scale graph analysis, and real-time stream analytics across clusters of machines. It also provides a scalable environment for implementing machine learning algorithms and predictive model development on massive datasets.
The engine incorporates relational query execution, graph data manipulation, and continuous data flow processing. It includes capabilities for distributed job execution, interactive query shells, and the integration of user-defined functions.
The project includes distributed cluster security with network traffic encryption and supports metadata management via Hive metastore integration.
