Elasticsearch Architecture

Elasticsearch is distributed, which means that indices can be divided into shards and

each shard can have zero or more replicas.

Each node hosts one or more shards and acts as a coordinator to delegate operations to the correct shard(s).

Rebalancing and routing are done automatically".

Elasticsearch — used to store data in the elastic database

Elasticsearch Node

Elasticsearch master node

controls the Elasticsearch cluster processing one cluster state at a time and

broadcasting the state to all other nodes.

The master node is in charge of all clusterwide operations,

including the creation and deletion of indexes.

Elasticsearch data node

contains data and the inverted index. This is the default configuration for nodes.

Elasticsearch client node

serves as a load balancer that routs incoming requests to various cluster nodes.
