Features of Neo4j

Aside from its support of the property graph model, Neo4j has several other features that make it a desirable data store. Here, we will examine some of those features and discuss how they can be utilized in a successful Neo4j cluster.

Clustering

Enterprise Neo4j offers horizontal scaling through two types of clustering. The first is the typical high-availability clustering, in which several slave servers process data overseen by an elected master. In the event that one of the instances should fail, a new master is chosen.

The second type of clustering is known as causal clustering. This option provides additional features, such as disposable read replicas and built-in load balancing, that help abstract the distributed nature of the clustered database from the developer. It also supports causal consistency, which aims to support Atomicity Consistency Isolation and Durability (ACID) compliant consistency in use cases where eventual consistency becomes problematic.
