Data Science Stack with MongoDB and RStudio
This document discusses using RStudio server with MongoDB to enable data science work on MongoDB data. Key points: - Fliptop uses MongoDB to store sales lead, opportunity, and contact data from their CRM. They also aggregate additional data sources. - They use RStudio server to pull MongoDB data into R data frames to enable exploring, analyzing, and prototyping machine learning algorithms on the data in an interactive way. - The rmongodb package allows transforming MongoDB data into R data frames. This allows working with the data in R for tasks like text processing, algorithm prototyping, and insights extraction.

Data Science Stack with MongoDB and RStudio
- 1. Data Science Stackwith MongoDB and RStudio Building up an easy data science platform with RStudio server on top of your MongoDB Winston Chen – Lead Software Engineer
- 2. What does Fliptopdo? • Predictive Lead Scoring, using data science – Pull opportunity/lead/contact data from CRM – Aggregate company data and social data from various data sources and the internet – Over 3000 signals – Build conversion/revenue model – Predict lead conversion and revenue
- 3. Our Platform Stack •Java/Scala • Liftweb • JMS/Storm • MongoDB/MySql
- 4. Our Machine LearningStack • Python • Numpy/Scipy/Pandas • Bottle (RESTful Server)
- 5. So, where isR then? • Problem: – Data is stored in MongoDB • Sales Lead Data • Sales Opportunity Data • Sales Contact Data – It’s hard to view/digest/process data on the fly using MongoDB console • (X) Text processing for insight extraction? • (X) Prototype cool machine learning algorithms on the fly? • Solution: – R and Rstudio Server • Why not scala? • Why not python/ipython
- 6. MongoDB Console &Query

- 8. Pull MongoDB datainto R data frame • rmongodb (https://github.com/gerald-lindsly/rmongodb) Transform Into a R data-frame
- 9. 1 – Getthe total count of your data set
- 10. 2 – ConstructVectors for each column
- 11. 3 – Loopthrough curser and insert values Where are my apply functions? - Too bad. We are using mongo cursor :P
- 12. 4 – Gointo sub bson block to extract data (optional)
- 13. 5 – Constructdata frame and return You are able to get the full example code here: http://goo.gl/tlyyXp We now have a data frame to play with from MongoDB bson.
- 14. This is NOTa BIG DATA Stack • It takes around 1 min to process 900Mb+ of bson from Mongo. • NOT BIG data stack – Data should fit into the ram • Most of the data in the business world is not big anyways. • It works fine for us (m1.large machine in AWS) – CRM data is never big, not even after we pull in 3000+ additional signals. – The term ‘Big-Data’ is seriously overrated, ‘Data Science’ however, is the key term here.
- 15. @Fliptop, we nowuse Rstudio to do • Data Insight Extraction • Algorithm prototyping
- 16. If you REALLYwant BIG Data • Look into: HDFS + Pig/Hive + Hue (any other suggestion from the audience here?)
