Python in an evolving enterprise system: Integration solutions with Hadoop

Excerpt

In 2011, we moved our data pipeline to a Hadoop stack in order to enable horizontal scalability for future growth. However, our optimization tools used for data exploration, aggregations, and general data hackery are built in Python. Over the past few months, we evaluated multiple solutions for integrating Python with Hadoop. In our talk, we'll explore the different Python-Hadoop integration options, share our evaluation process and best practices, and invite an interactive dialogue of lessons learned.

Description

Our data pipeline is growing like crazy, processing more than 30 terabytes of data every day and more than tripling in the last year alone. In 2011, we moved our data pipeline to a Hadoop stack in order to enable horizontal scalability for future growth. Our optimization tools used for data exploration, aggregations, and general data hackery are critical for updating budgets and optimization data. However, these tools are built in Python, and integrating them with our Hadoop data pipeline has been an enormous challenge. Our continued explosive growth demands increased efficiency, whether that’s in simplifying our infrastructure or building more shared services. Over the past few months, we evaluated multiple solutions for integrating Python with Hadoop including using Hadoop Streaming, PIG with Jython UDFs, writing MapReduce in Jython, and of course, why not just do it in Java? In our talk, we’ll explore the different Python-Hadoop integration options, share our evaluation process and best practices, and invite an interactive dialogue of lessons learned.

Speaking experience

Will be giving this talk for the first time at PyData SV 2013 in March.
