What database is used for Elasticsearch

(Baumann) #1

Hi all,

An Elasticsearch cluster can contain multiple nodes. A node can have one or many Primary shards and replica shards. A shard is a Lucene index.

What database is used to store the actual data (documents)? Is it a database shipped with Lucene or is the database part of Elastic Search?

It's stored as stored fields inside Lucene. (On disk that means).
No database behind the scene.
