ElasticSearch is an open source project that has been rising in popularity and has become a standard component of most modern infrastructures. Its integration in Drupal has often been tied to the Search API module and compared with Apache Solr, but in my opinion these approaches miss the biggest benefits that ElasticSearch has to offer: a simple but powerful API, flexible data structures, painless distributed setup, and much more. Taking full advantage of ElasticSearch requires more understanding, from technical aspect like aggregations and nested objects to conceptual ones like what makes a good autocomplete suggestion. This workshop should give you a good idea of the possibilities made available by ElasticSearch, and will give you the tools needed to integrate it in your next project - whether it is Drupal based or not.
