The course aims at providing: • Knowledge of the main technological characteristics of the infrastructures and distributed frameworks used to deal with big data (e.g., Hadoop and Spark). • Ability to write distributed programs to process and analyze big data by means of big data frameworks (Spark RDD- and DataFrame-based programming). • Ability to implement scalable data analytics processes, based on data mining and machine learning algorithms, for internet applications (e.g., network traffic data analysis). • Knowledge of the (relational and non-relational) databases systems that are used to store and query big data.

Basic object-oriented programming skills Knowledge of the Python programming language

Lectures (42 hours) • Introduction to Big data: characteristics, problems, opportunities (3 hours) • Hadoop and its ecosystem: infrastructure and basic components (3 hours) • Apache Spark Architecture (3 hours) • Spark RDD- and dataset-based programming paradigm (16.5 hours) • Streaming data analysis: Spark Streaming (3 hours) • Data mining and Machine learning libraries: Spark MLlib (3 hours) • Graph analytics: Spark GraphX and GraphFrame (3 hours) • Databases for Big data: data models, design, and querying (e.g., HBase and MongoDB) (4.5 hours) • Introduction to network traffic data analytics (3 hours) Laboratory activities (18 hours) • Developing of applications for big data analytics based on Spark (18 hours)

The course consists of Lectures (42 hours) and Laboratory sessions (18 hours). The laboratory sessions are focused on the main topics of the course (Apache Spark, MLlib, NoSQL databases). The Laboratory sessions allow experimental activities on the most widespread big data frameworks.

Copies of the slides used during the lectures, examples of exercises, and manuals for the activities in the laboratory will be made available. All teaching material is downloadable from the course website or the Teaching Portal. Reference books: • Matei Zaharia, Bill Chambers. Spark: The Definitive Guide (Big Data Processing Made Simple).

Exam: Individual essay; Computer-based written test using the PoliTo platform;

Exam: Written online test (by using the Exam platform + Respondus); Individual essay The exam aims at assessing (i) the ability of the students to write distributed programs to process and analyze big data by means of novel programming paradigms (the Spark RDD- and dataset-based programming paradigm) and frameworks and (ii) the knowledge of the students of the main concepts related to the big data topic and the technological infrastructures and distributed systems, including scalable relational and non-relational databases systems, that are used to deal with big data. The exam includes two mandatory parts. The two mandatory parts are (i) a written online test (based on Exam+Respondus) and (ii) the evaluation of an individual report on the practices assigned during the course. PART I - WRITTEN ONLINE TEST The written test (online version with Exam+Respondus platforms) lasts 2 hours and it is composed of two subparts: - 2 programming exercises (Spark RDD- and DataFrame-based programming) , structured as open questions (27 points) - 2 multiple choice questions on all the topics addressed during the course (4 points) The programming exercises aim at evaluating the ability of the students to write distributed programs to analyze big data by means of the novel programming paradigms that are introduced in the course. The multiple choice questions are used to evaluate the knowledge of the theoretical concepts of the course and in particular the knowledge of the characteristics of the main technological infrastructures and distributed systems (Hadoop and Spark), including scalable relational and non-relational databases systems, that are used to deal with big data. The evaluation of the programming exercises is based on the correctness and efficiency of the proposed solutions. For each multiple choice question, the students achieve two points if the answer is correct and zero points if the answer is wrong or missing. The written online test is closed book. - Books, notes, and any other paper material are not allowed. - Electronic devices of any kind (PC, laptop mobile phone, calculators, etc.), apart from the PC used to take the test, are not allowed. The maximum grade for the written online test is 31. PART II - INDIVIDUAL REPORT The second part of the exam consists in preparing an individual report on the practices assigned during the course and developed in laboratories. The report aims at evaluating the ability of the students to implement data analytics processes for analyzing big data. The evaluation of the report is based on the clarity of the report and on technical correctness and efficiency of the proposed and implemented solutions. The maximum grade for the individual report is 31. FINAL GRADE The exam is passed if (i) the grade of the written online test is greater than or equal to 18 points and (ii) the grade of the individual report is greater than or equal to 18 points. The final grade is a weighted average between the evaluations of the written test (80%) and the individual report (20%). Specifically, the final grade is given by the following weighted average: grade of the written test*0.8 + grade of the report*0.2
