  • **Spark Performance:** Running the TeraSort benchmark (1TB dataset) completed in 18 minutes. This demonstrates the parallel processing capabilities of the cluster. Apache Spark details the Spark framework.
  • **Hive Query Performance:** Complex SQL queries involving joins and aggregations on a 100TB dataset completed in an average of 5-15 minutes, depending on the query complexity. Optimizations such as partitioning and bucketing were applied. Apache Hive provides details on Hive's SQL-like interface.
  • **Cassandra Write/Read Latency:** Average write latency of 10ms and average read latency of 5ms at a sustained write rate of 100,000 operations per second. Apache Cassandra is a NoSQL database.
  • **Real-world performance (Log Analysis):** Analyzing a 1TB daily log file with complex pattern matching and aggregation took approximately 30 minutes.
  • **Real-world performance (Machine Learning):** Training a medium-sized machine learning model (e.g., a deep neural network for image recognition) on a 500GB dataset took approximately 6-12 hours. Utilized TensorFlow and GPU acceleration (see section 4).

These benchmarks are indicative and can vary based on data characteristics, configuration settings, and workload specifics. Proper tuning and optimization are crucial for maximizing performance. Performance Tuning provides guidance on optimization techniques.
