Understanding node services
When a node is running, a lot of services are managed by its instance. These services provide additional functionalities to a node and they cover different behaviors such as networking, indexing, analyzing and so on.
Getting ready
Every ElasticSearch server that is running provides services.
How it works...
ElasticSearch natively provides a large set of functionalities that can be extended with additional plugins.
During a node startup, a lot of required services are automatically started. The most important are:
- Cluster services: These manage the cluster state, intra-node communication, and synchronization.
- Indexing Service: This manages all indexing operations, initializing all active indices and shards.
- Mapping Service
