Transaction Semantics in Neptune - Amazon Neptune

Amazon Neptune is designed to support highly concurrent online transactional processing (OLTP) workloads over data graphs. The W3C SPARQL Query Language for RDF specification and the Apache TinkerPop Gremlin Graph Traversal Language documentation do not define transaction semantics for concurrent query processing. Because ACID support and well-defined transaction guarantees can be very important, we enforce strict semantics to help avoid data anomalies.

This section defines these semantics and illustrates how they apply to some common use cases in Neptune.
