Data Lake Analytics: Analyzing Millions of NYC Taxi Trips
Data Lake Analytics: Analyzing Millions of NYC Taxi Trips


All data today tends to be big data. Companies of all sizes are searching for platforms and tools to manage their rapidly growing data sets. However, despite the number of platforms available, bringing heterogeneous data into a homogenous data lake environment is one of the most daunting aspects of any big data implementation.

Join Arjuna Chala, Sr Director of HPCC Systems as you walk through a real-world case study to illustrate how to manage disparate data with ease and efficiency. Arjuna will walk through how to profile, transform, aggregate, and analyze New York City taxi data to extract some important conclusions –Traffic volume by day, hour, and week for a given area; Number of trips to and from an Airport; Cash transactions vs Credit; and much more using the completely free, open source HPCC Systems platform built by one of the largest data aggregating companies in the world. LexisNexis Risk Solutions built HPCC Systems on the premise that big data is actually a solution and not a problem. Harvesting large data from thousands of sources helps in incorporating a learning-based approach to handling data.

In this talk, you will learn how to:

•Improve the speed and accuracy of the transformation, cleaning, normalization, and aggregation processes
•Enable efficient use of developer resources and development budgets
•Facilitate the use of standard hardware, operating systems, and protocols
