Description:

Every day, over half a billion tweets are generated. And processing them for analytics can seem to be a Herculean task. We at Microsoft deal with such social data sets on a daily basis, and in this webcast we share our experiences building a real time search, analytics, and trends pipeline over social data, with the power of Elasticsearch, Azure, and Spark.

While Elasticsearch is highly scalable, fine tuning the architecture to respond in under 900 milliseconds for 45 billion documents (while indexing) is still a tough task. We will discuss several aspects including design of search cluster, experimentation setup for performance tuning, learnings from cloud services, fault tolerance, monitoring, customer facing APIs, lowering costs and other best practices, to get the most out of your hardware.

Next, we talk about enabling analytics over this data using stream processing. We will discuss annotating tweets with natural language processing tools and text-based classifiers, doing temporal analytics, and eventually building applications like topical trend generation (for example, TV show trends for Xbox). Such a case study will be a good example of bridging the gap between the fields of data science and data engineering.
