El objetivo de este capítulo es ponerte al día sobre PySpark y Spark, dándote suficiente información para que te sientas cómodo con los tutoriales del resto del libro. Empecemos por el principio. ¿Qué es exactamente Spark? Desarrollado originalmente en la UC Berkeley en 2009, Apache Spark es un motor analítico de código abierto para big data y aprendizaje automático. Poco después de su lanzamiento, las empresas de muchos sectores lo adoptaron rápidamente, y potencias como Netflix, Yahoo y eBay lo implementan a gran escala para procesar exabytes de datos en clústeres de muchos miles de nodos. La comunidad Spark también ha crecido rápidamente, abarcando a más de 1.000 colaboradores de más de 250 organizaciones.
