Neo4j this week unveiled its new Infinigraph structure that it says addresses one of many elementary challenges within the scaling of graph databases: the issue in maintaining a graph database’s construction in reminiscence as the amount of knowledge will increase. The innovation will unleash new scale for operational use instances, akin to fraud detection, and likewise bolster rising GraphRAG workloads, the corporate says.
Because of the best way they retailer information in linked nodes, graph databases are in a position to run some varieties of data-intensive workloads an order of magnitude extra effectively than conventional relational databases. As an alternative of performing compute-intensive joins to determine connections in a given information set–akin to individuals who have labored with a selected firm–a property graph like Neo4j’s can discover the similarities with a easy question, for the reason that information was initially modeled upon connections to start with. Along with getting solutions faster, graphs can save CPU cycles and energy and expense that entails.
Nevertheless, there are limitations to the graph method. For starters, graph databases work greatest when the complete graph might be loaded into reminiscence. That isn’t an issue for smaller information units, but it surely turns into a difficulty as the dimensions of the information grows. Neo4j was initially constructed to run on massive symmetric multi-processor (SMP) scale-up machines with a lot of reminiscence. It began creating a distributed, scale-out model of its database about 5 years in the past to deal with clients with very massive datasets. Whereas it made progress within the distributed world, the elemental limitations in utilizing graphs in a distributed structure stay.

Neo4j’s launch of Infinigraph represents an revolutionary answer to this dilemma. The corporate determined to compromise on the varieties of information that it separated to run on separate nodes, or sharded. As an alternative of splitting the core elements of its property graph structure–specifically the nodes and relationships–and sharding them out to separate machines in a cluster, with Infinigraph, the corporate elected to shard solely properties related to the nodes and relationships, thereby maintaining the nodes and relationships intact in the identical reminiscence house.
Properties in a graph database are the values related to a node or a relationship. Every node or relationship can have any variety of properties related to it. As an example, a node for a “individual” might need properties akin to “title” or “age,” whereas the connection part might need extra proprieties, like a particular date or location for a “WorksAt” property.
With Infinigraph, Neo4j is introducing property sharding, which permits the nodes and relationships to remain on a single server whereas the possibly voluminous properties are saved in separate nodes in a cluster, says Dan McGrath, Neo4j’s VP of product administration for cloud.
“One of many nice challenges within the database business has been scaling transactional and analytical graph workloads with out sacrificing efficiency, construction, or ease of use,” McGrath wrote in a weblog publish. “Infinigraph structure solves this problem by distributing a graph’s property information throughout the servers in a cluster. Property sharding permits the graph itself to stay logically complete; queries behave as anticipated, and functions scale with out code adjustments or handbook workarounds.”
In response to McGrath, every entity within the Neo4j graph shard has precisely one corresponding entity in a property shard, and when a question requests properties, the system mechanically fetches them from the best shard, whereas traversal stays native to the topology shard.
“The entire system runs in an autonomous cluster,” he wrote. “The graph shard kinds a daily Raft group, making certain availability and failover. Property shards might be scaled independently by including replicas, which gives them with excessive availability, a brand new function launched for property sharding within the Neo4j autonomous cluster.”
No adjustments are required to the graph database functions with Infinigraph, Neo4j says, and Cypher queries work as earlier than. Nodes and relationships are written to the graph shard, whereas the particular properties of the nodes and relationships could also be written to a distinct shard. The developer nonetheless is writing only a single question, and the database figures out which property shard to fetch the information from.
This method brings many advantages, McGrath says, together with the potential to scale a graph past 100TB of knowledge; the potential to embed billions of vectors immediately within the graph; eliminating the necessity for ETL pipelines; all whereas sustaining full ACID compliance.
Neo4j says this new method will assist groups conduct operational and analytic operations on the identical time, together with detecting fraud and analyzing fraud rings from the identical dataset, or producing real-time buyer suggestions whereas analyzing many years of buyer information and behavioral traits. “They’ll energy GenAI assistants, compliance methods, and transactional functions on one constant supply of reality,” the comapny says.
There are some limitations with the brand new method, nonetheless. The variety of property shards is fastened at creation within the first model of Infinigraph, and it doesn’t but assist computerized rebalancing. Neo4j recommends Infinigraph be used for property-heavy graphs.
Infinigraph is accessible now in Neo4j’s self-managed providing. It can quickly be out there in Neo4j AuraDB, the corporate’s cloud-native platform.
