Why Elasticsearch SQL ?edit

Native integration
Elasticsearch SQL is built from the ground up for Elasticsearch. Each and every query is efficiently executed against the relevant nodes according to the underlying storage.
No external parts
No need for additional hardware, processes, runtimes or libraries to query Elasticsearch; Elasticsearch SQL eliminates extra moving parts by running inside the Elasticsearch cluster.
Lightweight and efficient
Elasticsearch SQL does not abstract Elasticsearch and its search capabilities - on the contrary, it embrases and exposes to SQL to allow proper full-text search, in real-time, in the same declarative, succint fashion.
