PostgreSQL – new jsonb feature exploration – insert, query, index

In this post, I will explore the (not really new) postgreSQL jsonb feature as my objective is to compare nosql performance in real scenarii.

  • postgreSQL 9.4.4 installed (you can check by issuing the following : select version();)
  • pgAdmin installed
  • this runs on a HP probook 6560b
    • Processor Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz, 2501 Mhz, 2 Core(s), 4 Logical Processor(s)
    • 16 G of ram

Exploring GraphDB – Access Neo4J with .net driver (Create, Delete and Match)

Still on my path to

“what is GraphDB and what are its limitations… from the eyes of a developer”

I had to access it from code. I choose to do it in .net and first created a simple access library that I will surely evolve during my learning. (you can check it here : CExtensions-Cypher). I also created a feed for this on Myget : MyGet cextensions-cypher feed. As of this writing I used version 0.1.0-CI00001. (so early birds, be patient or contribute)

Note : You can also simply connect to Neo4j by just adding the package Neo4j.Driver.

If you want to use my library with VS2015, just add the feed in your Nuget Package Manager settings (Package sources) and add it to your project.

1) from there :

  • you can choose the free community edition
  • then select the Other Releases link
  • I choosed Neo4j 3.0.3 for windows 64 bit, but this depend on your platform.
