Joola supports ElasticSearch as a Data Store.
Elasticsearch is a search server based on Lucene. It provides a distributed, multitenant-capable full-text search engine with a RESTful web interface and schema-free JSON documents. Elasticsearch is developed in Java and is released as open source under the terms of the Apache License.
To use ElasticSearch with your Joola cluster:
$ npm install joola.datastore-elasticsearch
In your configuration add the following:
store: elasticsearch: enabled: true host: localhost log: trace
