This document discusses using RFX (Reactive Function X), a design pattern and collection of open source tools, to solve fast data problems. It presents an example of using RFX for web analytics to count pageviews and unique users and detect DDOS attacks. The RFX approach applies the BEAM methodology for agile data warehousing. It demonstrates RFX concepts like event data actors, agents, collectors, routers, processors, storage and reactors using a pageview analytics demo with source code on GitHub.

5. 1 - BEAM✲ methodology

6. 1 - BEAM✲ methodology for Agile Data Warehouse
BEAM✲ stands for Business Event Analysis &
Modelling, and it’s a methodology for gathering business
requirements for Agile Data Warehouses and building
those warehouses.
It was developed by Lawrence Corr (@LawrenceCorr) and
Jim Stagnitto (@JimStag), and published in their book Agile
Data Warehouse Design: Collaborative Dimensional
Modeling, from Whiteboard to Star Schema.

7. Example with BEAM✲

8. Goal: Modeling all business events and put into a database
in agile way

9. 2 - Fast Data

10. Introduction to Fast Data

12. 3 - Problems in Practice

13. Problems
“Fast Data in web analytics”
1. Counting pageview of website
2. Counting unique user of website
3. Sending email when pageview is unnormal (simple DDOS
attack detection)

14. 4 - Thinking with RFX

15. ● A design pattern to solve big fast data problems
● A collection of Open Source Tools
● The mission of RFX
1. Build data product quickly with design patterns
2. Apply BEAM✲ for agile data pipeline
3. React to critical events in near-real-time
What is RFX or Reactive Function X ?

16. Philosophy of RFX

17. How to solve problems with RFX ?

18. “Fast Data in web analytics”
1. Counting pageview of website
2. Counting unique user of website
3. Sending email when pageview is unnormal (simple
DDOS attack detection)

19. Apply RFX into Pageview Analytics
1.1. Event data actor: a web user
1.2. Event data agent: RFX-track-js
1.3. Event data collector: RFX-track-server
1.4. Event data router: Apache Kafka
1.5. Event data processor: RFX-stream
1.6. Event data storage: Redis, MySQL
1.7. Event data query: RFX-data-api
1.8. Event data reactor: RFX-reactor
