What storage engine does elastic search uses?


(Dimitris Bozelos) #1

Hello

I understand ElasticSearch implements a document storage on top of Lucene. Could someone point to me some resources on the implementation of the storage engine? It is not very obvious where this may be found in the docs.

Lucene uses this class to write stored fields in a compressed format ... it has some documentation describing how it works:
