Clustering and high availability

A cluster is a set of nodes (servers) that hold all the data together and provide the ability to index and to search for indexed nodes.

Automatic node recovery

When a node clumps for any other reason, violent or not, the master node responds by replacing the node with a replica and changing the shard. This is to protect the cluster from data loss by ensuring that each shard is fully replicated.

Automatic data rebalancing

The Elasticsearch cluster master node automatically determines when to move garments between nodes and automatically assigns which nodes to align the sharks and the cluster.

Horizontal scalability

As it grows, the elasticsearch grows accordingly. Include data and usage cases. If you run out of resources, add a node to your cluster for efficiency and reliability. Additionally, when a node is added to your cluster, duplicate segments will be assigned automatically in the future.

Rack awareness

You can use custom node features as conscious features to enable Elasticsearch to take into account your physical hardware configuration when shards allow.

Cross-datacenter replication

Cross-datacenter replication has been a requirement for mission-critical applications on Elasticsearch for some time. With cross-cluster replication in Elasticsearch, no additional technologies are needed to replicate data across Elasticsearch clusters, geographies, and datacenters.
