Sample Code for "Large Scale Metrics Analysis in Ruby"

This repository contains annotated example code to accompany the AWS re:Invent 2015 presentation DEV309: "Large Scale Metrics Analysis in Ruby".

mapper.rb and reducer.rb

These are executable Ruby files that can be used with Hadoop Streaming on Amazon Elastic MapReduce clusters. They're made to work with a particular log file format shown in the presentation. However, like most of these examples, they can serve as useful guideposts when you design your own purpose-built mappers and reducers.

log_processor.rb and batching_example.rb

Shows an example of a control plane for log processing jobs, that can support job batching. Includes an example of how this control plane might be called for a simple example job.

redshift_operations.rb

Shows some Redshift cluster management operations, based on the pattern used in the presentation.
