JPPF: an Java Open Source solution for parallel processing



JPPF (http://www.jppf.org/) is a Java framework which can help to implement and run a parallel Java program. It allows a Java application to run independent parts of it on different machines in parallel in order to dramatically reduce their processing time. It is useful to split a computing-intensive Java application into several mostly independent parts (which are typically called tasks).
JPPF is Open Source and released under the Apache license 2.0.
These are the main features of this framework:
  • Allows a grid (a server, to which any number of execution nodes are attached.) to be up and running in minutes.
  • Provides a simple programming model that abstracts the complexity of distributed and parallel processing .
  • It's an highly scalable (from small to large networks) and distributed framework for the parallel execution of cpu intensive tasks.
  • Provides seamless integration with the most popular J2EE application servers (IBM WebSphere, JBoss, WebLogic, etc.).  
  • Comes with fault-tolerance and self-repair capabilities to ensure service and reliability.
  • It's cross-platform (of course, it's pure Java).
  • Provides both graphical and programmatic tools for fine-grained monitoring and administration.
The figure below (taken from the official website) shows a typical JPPF topology:


In the real world there are a lot of examples of application of parallel processing (scientific research, 3D rendering, data mining, AI, etc.) and I think that it could be preferred to concurrency in other boundaries when you have good hardware availability.
I discovered this framework more than one year ago and started to make a proof of concept afterhours in order to understand possible benefits applying it to uncommon applications. As soon as possible I will share the results and my opinion on this.

Exporting InfluxDB data to a CVS file

Sometimes you would need to export a sample of the data from an InfluxDB table to a CSV file (for example to allow a data scientist to do some offline analysis using a tool like Jupyter, Zeppelin or Spark Notebook). It is possible to perform this operation through the influx command line client. This is the general syntax: sudo /usr/bin/influx -database '<database_name>' -host '<hostname>' -username '<username>'  -password '<password>' -execute 'select_statement' -format '<format>' > <file_path>/<file_name>.csv where the format could be csv , json or column . Example: sudo /usr/bin/influx -database 'telegraf' -host 'localhost' -username 'admin'  -password '123456789' -execute 'select * from mem' -format 'csv' > /home/googlielmo/influxdb-export/mem-export.csv

jOOQ: code generation in Eclipse

jOOQ allows code generation from a database schema through ANT tasks, Maven and shell command tools. But if you're working with Eclipse it's easier to create a new Run Configuration to perform this operation. First of all you have to write the usual XML configuration file for the code generation starting from the database: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <configuration xmlns="http://www.jooq.org/xsd/jooq-codegen-2.0.4.xsd">   <jdbc>     <driver>oracle.jdbc.driver.OracleDriver</driver>     <url>jdbc:oracle:thin:@dbhost:1700:DBSID</url>     <user>DB_FTRS</user>     <password>password</password>   </jdbc>   <generator>     <name>org.jooq.util.DefaultGenerator</name>     <database>       <name>org.jooq.util.oracle.OracleDatabase</name>     ...

Turning Python Scripts into Working Web Apps Quickly with Streamlit

 I just realized that I am using Streamlit since almost one year now, posted about in Twitter or LinkedIn several times, but never wrote a blog post about it before. Communication in Data Science and Machine Learning is the key. Being able to showcase work in progress and share results with the business makes the difference. Verbal and non-verbal communication skills are important. Having some tool that could support you in this kind of conversation with a mixed audience that couldn't have a technical background or would like to hear in terms of results and business value would be of great help. I found that Streamlit fits well this scenario. Streamlit is an Open Source (Apache License 2.0) Python framework that turns data or ML scripts into shareable web apps in minutes (no kidding). Python only: no front‑end experience required. To start with Streamlit, just install it through pip (it is available in Anaconda too): pip install streamlit and you are ready to execute the working de...
