About this talk

Denny Lee, Technology Evangelist with Databricks, will provide a jump start into Apache Spark and Databricks. Spark is a fast, easy to use, and unified engine that allows you to solve many Data Sciences and Big Data (and many not-so-Big Data) scenarios easily. Spark comes packaged with higher-level libraries, including support for SQL queries, streaming data, machine learning, and graph processing. We will leverage Databricks to quickly and easily demonstrate, visualize, and debug our code samples; the notebooks will be available for you to download. This introductory level jump start will focus on the following scenarios: - Quick Start on Spark: Provides an introductory quick start to Spark using Python and Resilient Distributed Datasets (RDDs). We will review how RDDs have actions and transformations and their impact on your Spark workflow. - A Primer on RDDs to DataFrames to Datasets: This will provide a high-level overview of our journey from RDDs (2011) to DataFrames (2013) to the newly introduced (as of Spark 1.6) Datasets (2015). - Just in Time Data Warehousing with Spark SQL: We will demonstrate a Just-in-Time Data Warehousing (JIT-DW) example using Spark SQL on an AdTech scenario. We will start with weblogs, create an external table with RegEx, make an external web service call via a Mapper, join DataFrames and register a temp table, add columns to DataFrames with UDFs, use Python UDFs with Spark SQL, and visualize the output - all in the same notebook.
