  • Deep Dive: Apache Spark Memory Management Deep Dive: Apache Spark Memory Management Andrew Or Recorded: Jun 15 2016 43 mins
    Memory management is at the heart of any data-intensive system. Spark, in particular, must arbitrate memory allocation between two main use cases: buffering intermediate data for processing (execution) and caching user data (storage). This talk will take a deep dive through the memory management designs adopted in Spark since its inception and discuss their performance and usability implications for the end user.

  • Enabling Exploratory Analysis of Large Data with Apache Spark and R Enabling Exploratory Analysis of Large Data with Apache Spark and R Hossein Falaki Recorded: May 19 2016 60 mins
    R has evolved to become an ideal environment for exploratory data analysis. The language is highly flexible - there is an R package for almost any algorithm and the environment comes with integrated help and visualization. SparkR brings distributed computing and the ability to handle very large data to this list. SparkR is an R package distributed within Apache Spark. It exposes Spark DataFrames, which was inspired by R data.frames, to R. With Spark DataFrames, and Spark’s in-memory computing engine, R users can interactively analyze and explore terabyte size data sets.

    In this webinar, Hossein will introduce SparkR and how it integrates the two worlds of Spark and R. He will demonstrate one of the most important use cases of SparkR: the exploratory analysis of very large data. Specifically, he will show how Spark’s features and capabilities, such as caching distributed data and integrated SQL execution, complement R’s great tools such as visualization and diverse packages in a real world data analysis project with big data.

  • Not Your Father's Database Not Your Father's Database Vida Ha Recorded: Apr 7 2016 51 mins
    This session will cover a series of use cases where you can store your data cheaply in files and analyze the data with Apache Spark, as well as use cases where you want to store your data into a different data source to access with Spark DataFrames. Here’s an example outline of some of the topics that will be covered in the talk:

    Use cases to store in file systems to use with Apache Spark:

    1. Analyzing a large set of data files.
    2. Doing ETL of a large amount of data.
    3. Applying Machine Learning & Data Science to a large dataset.
    4. Connecting BI/Visualization tools to Apache Spark to analyze large datasets internally.

    Use cases to store your data into databases for use with Apache Spark:

    1. Random access, frequent inserts, and updates of rows of SQL tables. Databases have better performance for these use cases.
    2. Supporting Incremental updates of Databases into Spark. It’s not performant to update your Spark SQL tables backed by files. Instead, you can use message queues and Spark Streaming or doing an incremental select to make sure your Spark SQL tables stay up to date with your production databases.
    3. External Reporting with many concurrent requests. While Spark’s ability to cache your file data in memory will allow you to get back to fast interactive querying, that may not optimal for supporting many concurrent requests. It’s better to use Spark to ETL your data to summary tables or some other format into a traditional database to serve your reports if you have many concurrent users to support.
    4. Searching content. A Spark job can certainly be written to filter or search for any content in files that you’d like. ElasticSearch is a specialized engine designed to return search results quicker.
