BigData - Blossom Module template for Magnolia CMS

Demonstrates how to extend Magnolia CMS behaviour for bigdata and mathematical operations, adding support to R-scripts and Python* (through reticulate) in Magnolia CMS.

Based on Magnolia 5.6

Features

Java is and amazing language but it has several problems to analyze multidimensional data. That's why Python and R are "better" to resolve scientific problems.

The Bigdata blossom module allows you to create your own scripts and test them against an R Engine. The aim for this it's providing Magnolia CMS with a valid mathematical and statistic tool to manage big amounts of numerical data and create customize calcs for bigdata and machine learning. It will let you have a dashboard and sandbox as an app, and create your customized modules as blossom components, rest api or native spring MVC/REST components

Adds R-engine app to desktop for live programming in r

Includes basic executable examples in r
Adds and extensible way of components for the web, like chart and remote r execution
Provides Standalone Spring MVC execution out of the blossom module component chain
Provides Rest end points
Provides Hightchart Blossom components with asyncronous data

Provides Remote R script execution as Blossom component
Includes a basic sandbox web template for live testing and quick component check
Provides a valid postman template (remember to change your server host!)
Provides wrapping and helper classes for chart creation through Highcharts

Usage

Just compile the project and execute it as a magnolia bundle.

Download the full project with maven and java 1.8 already installed in your computer
Execute "compile task" or "install task". Avoiding checkstyle is enabled due to Magnolia checkstyle configuration problems. Will be solved in a future.
Deploy the generated war in your server
Works as a bundle. Copy the module into your project directly if you need it.

Base components and examples for bigdata analysis

Check com.albertosoto.magnolia.bigdata.spring.rest.RenjinStatsController for a basic example of executing r-code and map the results in java classes
Check com.albertosoto.magnolia.bigdata.spring.rest.RenjinActionsController for executing repository

R-Language & Python

Remember to learn R-language to use it. It's recommended to check info and CRAN packages as well as RENJIN dependency. Feel free to use any CRAN package as a maven dependency inside the module
Renjin is the heart of it. First execution will be slower than others. Check any CRAN dependency and it's evolution
At the moment of installation, Python execution is served as "reticulate" package and, right now, it has problems for execution. Will be solved as far as renjin solves it.
The "big" problem out-of-the-box is R plotting. Anyway you can use the example chart component provided through blossom chain. It's not blossom dependant (load data by rest).
