Advanced Web Metrics Project (PayPal) May’13 – Nov’13

Tools: HADOOP, Apache PIG, Apache HBase, Python

The idea here was to use technology to extract data from Paypal’s Central Application Logging (CAL)

repository for conversion analysis, error analysis, production triaging and historical trends. As the

volume of this data is humongous (20 GB per hour) a distributed big data processing framework such

as HADOOP was the most optimal solution. To handle the enormous amount of CAL data we built a tool

on top of Apache PIG regression (machine learning) was used for analyzing the CAL and then useful data

extracted from the Pig script was input into Apache HBase.

Metrics would be generated using Map-reduce programs and Pig scripts.

Improvement of 100bps in other words 32 Million in potential gains (based on 30 % conversion during retry) by determining unknown unknowns.
