So as someone who has heard about Elasticsearch for years and years, and seen all this, right this moment I've decided to see what it really is. On their home page, "Why use Elastic search?", the reasons are basically: * It's fast! * It does a lot of stuff! * It has some tools to visualize data! * It's distributed!! I have to say this is not very appealing to me since it sounds like something any database could do.
"Elasticsearch is a distributed, free and open search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured. Elasticsearch is built on Apache Lucene and was first released in 2010..."
I suggest understanding what it is first before comparing it to other databases.
