Query: Studio e confronto delle strutture di Apache Spark   English. This document is designed to study the data structures that can be
used in the Apache Spark framework and to evaluate the best performing ones to
implement solutions, in particular we will evaluate advantages / disadvantages
deriving from the use of Dataset for job creation. The observation of the
results provides further support in evaluating the use of Dataset as an
alternative to RDD, in order to understand its strengths and weaknesses. The
examination of the results is possible thanks to specifically designed and
implemented in Java 1.8 language. The execution of the jobs, entrusted to a
suitable distributed environment, will end with the comparison between
execution times and results obtained.
  Italiano. Il presente documento nasce allo scopo di studiare le strutture
dati utilizzabili nel framework Apache Spark e valutare quelle pi\`u
performanti per implementare soluzioni; valuteremo in articolare i vantaggi /
svantaggi derivanti dall'utilizzo dei Dataset nella progettazione dei job.
L'osservazione dei risultati fornisce ulteriore supporto nel valutare
l'utilizzo dei Dataset in alternativa a RDD, al fine di comprederne i punti di
forza e di debolezza. L'esame dei risultati \`e possibile in virt\`u di due
casi appositamente pensati e implementati in linguaggio Java 1.8. L'esecuzione
dei job, affidata a un adeguato ambiente distribuito, si concluder\`a con il
confronto tra tempi di esecuzione e risultati ottenuti.
