Paris Spark Meetup (Feb2015) ccarbone : SPARK Streaming vs Storm / MLLib / NextProductToBuy

  1. 1. Spark Meetup chez Viadeo Mercredi 4 février 2015 • 19h-19h45 : Présentation de la technologie Spark et exemple de nouveaux cas métiers pouvant être traités par du BigData temps réel. Cédric Carbone - Cofondateur d'Influans – cedric@influans.com -Spark vs Hadoop MapReduce -Spark Streaming vs Storm -Le Machine Learning avec Spark -Use case métier : NextProductToBuy • 19h45-20h : Extension de Spark (Tachyon / Spark JobServer). Jonathan Lamiel - Talend Labs – jlamiel@talend.com -La mémoire partagée de Spark avec Tachyon -Rendre Spark Interactif avec Spark JobServer • 20h-21h : Big Data analytics avec Spark & Cassandra. DuyHai DOAN - Technical Advocate at DataStax – duy_hai.doan@datastax.com Apache Spark is a general data processing framework which allows you perform data processing tasks in memory. Apache Cassandra is a highly available and massively scalable NoSQL data-store. By combining Spark flexible API and Cassandra performance, we get an interesting combo for both real-time and batch processing.
  2. 2. Map Reduce ➜ Map() : parse inputs and generate 0 to n <key, value> ➜ Reduce() : sums all values of the same key and generate a <key, value> WordCount Example ➜ Each map take a line as an input and break into words • It emits a key/value pair of the word and 1 ➜ Each Reducer sums the counts for each word • It emits a key/value pair of the word and sum
