An interesting trend have been developing in the IT landscape over the past few years. Many new technologies develop and immediately latch onto the "Big Data" buzzword. And as older technologies add "Big Data" features in an attempt to keep up with the Joneses, we is seeing a blurring of t He boundaries between various technologies. Say you have search engines such as ElasticSearch or SOLR storing JSON documents, MongoDB storing JSON documents, or a P
