Big Data beyond Hadoop
• Real-time analytical processing (RTAP)
– Discover and explore data iteratively and interactively for real-time insights
• Advanced machine leaning and data mining (MLDM)
– Graph-parallel predictive analytics (non-SQL)
• Distributed in-memory analytics
– Exploit available main memory in the entire cluster for 100x speedup
RTAP: Real-Time Analytical Processing
Real-Time Analytical Processing (RTAP)
• Data ingested processed in a streaming fashion
• Real-time data queried and presented in an online fashion
• Real-time and history data combined and mined interactively
• Predominantly RAM-based processing
Advanced, Graph-Parallel MLDM
Advanced machine learning and data mining (MLDM)
• Information retrieval (e.g., page rank)
• Recommendation engine (e.g., ALS)
• Social network analysis (e.g., clustering)
• Natural language processing (e.g., NER)
• …
Graph parallel computations
• A sparse graph G(V, E)
• A vertex program P runs on each vertex in parallel
repeatedly
• Vertices interact along edges
Advanced, Graph-Parallel MLDM
