Spark is redefining the big Data ecosystem and opening doors to capabilities not available before. Comcast is moving in the direction of adopting Spark for several projects, ranging from real-time processing, data science, and large scale analytics, to the Xfinity personalization platform.
This talk will showcase some of the use cases and how we use Spark to solve many of the tough problems at Comcast scale.
1. Real time processing is a challenging topic, and historically we had to use a mixture of home-grown and off-the-shelf technologies to get a working model. We will talk about how we use Kafka to get events from over 40 million STBs, and hand over to Spark streaming which processes the events.
2. Data science is a very challenging field and more requirements pop up all the time. We are looking at Spark to build a reliable flexible framework that integrates with Hadoop, HBase, and Solr as well as provide ease of migration for data scientists who work in R and SAS.
3. Comcast provides personalized recommendations to its customers on the X1 platform. Our initial implementation was built on the Hadoop map-reduce framework using a batch computation model. When we wanted to explore how we can offer real-time recommendations, we looked to Spark because of its increased computational efficiency, and its ease in developing both streaming and batch processing solutions using the same code base.
In short, there are many fields that can profit from the plethora of capabilities provided by Spark.
