Neptune Analytics

Discover how Neptune Analytics accelerates complex graph algorithms by processing data in-memory, enabling fast, iterative exploration of large connected datasets. Learn when to use this tool alongside Neptune Database and how graph data flows into Neptune Analytics for powerful batch and investigatory workloads.

In the previous lesson, we explored operational graph workloads where Neptune Database serves live applications for recommendation engines, fraud scoring, identity resolution, and knowledge graphs. Those workloads are transactional in nature, optimized for point queries, short traversals, and durable writes that keep an application's graph state consistent. However, not all graph work fits this transactional mold. Some workloads demand fast, exploratory, algorithm-heavy analysis over large, connected datasets, iterating across millions of edges to detect communities, compute centrality scores, or discover hidden structural patterns. These investigatory tasks strain a transactional store because they require full-graph scans rather than targeted lookups.

AWS addresses this gap with Neptune Analytics, a purpose-built, in-memory graph analytics engine designed specifically for algorithmic and exploratory graph processing. Neptune Analytics complements Neptune Database rather than replacing it. The two services occupy different positions in the graph workload spectrum, much like the separation between an OLTP relational database and an OLAP data warehouse in the relational world.

This lesson covers four objectives. First, you will understand when Neptune Analytics is the correct architectural choice. Second, you will learn how its in-memory processing model accelerates iterative graph algorithms. Third, you will see how graph data flows into Neptune Analytics from multiple sources. Finally, you will understand how Neptune Analytics fits into the broader Neptune ecosystem as a prerequisite for Neptune ML.

Note: Neptune Analytics is not a general-purpose replacement for Neptune Database. AWS positions it as a complementary layer for analytical workloads that would otherwise degrade transactional performance if run against the operational store.

The following table clarifies the boundary between these two services across several decision dimensions.
