● History
○ Shay Banon created the precursor to Elasticsearch, called Compass, in 2004
○ While thinking about the third version of Compass he realized that it would be necessary
to rewrite big parts of Compass to "create a scalable search solution" So he created "a
solution built from the ground up to be distributed" and used a common interface, JSON
over HTTP, suitable for programming languages other than Java as well.
○ Shay Banon released the first version of Elasticsearch in February 2010.
