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
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
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).
A dummy web template it's included.
- Although the main concept of the project is not providing webcomponents there are base components as an example to work with it.
This directory is a Magnolia 'blossom module' delivered as a full project.
