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.

Prerequisite:
  • 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

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.
