ElasticSearch is an open-source search engine platform designed using Lucene library to produce a distributed and multitenant capable search engine with HTTP web interface. It’s developed using Java programming language.
Compass is a precursor to Elasticsearch, and it was created by Shay Banon back in the year 2004. Compass was later on created to its bigger version to provide a scalable search solution. This was what brought the first version of Elasticsearch. In 2012, the commercial version of ElasticSearch was then released to the market by Elastic NV.
