In this webcast, Patrick Wendell from Databricks will be speaking about Apache Spark's new 1.6 release.
Spark 1.6 will include (but not limited to) a type-safe API called Dataset on top of DataFrames that leverages all the work in Project Tungsten to have more robust and efficient execution (including memory management, code generation, and query optimization) [SPARK-9999], adaptive query execution [SPARK-9850], and unified memory management by consolidating cache and execution memory [SPARK-10000].
Chief Technologist, Ruhollah Farchtchi gives a presentation at Spark Summit East, 2016 on the Interactive Visualization of Streaming Data Powered by Spark.
Much of the discussion on real-time data today focuses on the machine processing of that data. But helping humans visualize real-time streams is just as important. Visualizing real-time data introduces new UX and usability challenges for any developer embedding analytics into applications, especially when the target end users are business users and not data scientists. Self-service, interactive, subsecond response time to ad hoc queries — these are the new UX requirements for any enterprise visualizing real-time data. Streaming data also lends itself to new paradigms of interaction with the stream itself, like being able to pause, rewind and replay a stream. This talk is a case study in how and why Zoomdata built a “Data DVR” capability using Spark and Spark Streaming. We will describe the required user experience, the overall architecture and the specific use of Spark and Spark Streaming. We will describe the design considerations that led us to choose Spark Streaming over alternatives like Storm. We will show how end users configure the real-time increment and a historical retention window without writing any code themselves. We will also show how pause, rewind, replay is implemented in Spark and how the solution supports both real-time and historical analysis in the same architecture. Attendees will walk away with knowledge of Spark Streaming and how users can interactively work with streaming data. They will develop familiarity with the challenges of a lambda architecture and providing a consistent analytic experience over streaming and historical data.

We are very well aware that companies like Facebook, Twitter, Whatsapp deal with datasets in the range of 100's of Petabytes and more. However not all datasets are that big. Did you know that all english pages of Wikipedia amount to just 49 GB uncompressed text data? Likewise, there are a large amount of datasets ranging from customers data to events and transactions which do not exceed the low Terabyte range.
In this webinar we will discuss how to process data in this range both for interactive queries as well for batch processing. We will look at what tradeoffs can be made by tuning the architecture with SSD and RAM. And which distributed computing paradigm work best for this datasets and their typical workloads. We will revision the concepts of data locality, data replication and parallel computing for this specific class of datasets.
