Documentation for internals and architecture of Elasticsearch

2014-11-19 Thread Rahul Khengare 
Hi All,

When we provides documents or data objects to Elasticsearch using REST 
APIs. Elasticsearch store the data to local store or any node in ES cluster.

I want to understand how elasticsearch store the data internally.
Is there any documentation available on architecture and storing mechanism. 

Thanks in advance.

Integrating elasticsearch and kibana with PostgreSQL

2014-11-10 Thread Rahul Khengare 
Hi All,

I have source input which stores data in PostgreSQL database in JSON format.
I want to perform the analytical operation on data present in PostgreSQL 
and visualize results of operations.

I have found one open source analytical tool called Kibana (integrated with 
elasticsearch) which will visualize the data.
http://www.elasticsearch.org/overview/kibana/

we can provide data present in PostgreSQL to elastic search through use of 
jdbc-river
https://github.com/jprante/elasticsearch-river-jdbc/wiki/Step-by-step-recipe-for-setting-up-the-river-with-PostgreSQL

I am trying to integrate PostgreSQL, elasticsearch and Kibana to perform 
analytical operations and visualize data.

Anybody tried something like that, your views and suggestion will be useful.
Thanks in advance
