TigerGraph Glossary

A quick reference guide to the terminology and components mentioned throughout this book.

Term	Definition
GPE	Graph Processing Engine. The heart of TigerGraph that executes GSQL queries and manages parallel traversals.
GSE	Graph Storage Engine. Manages the physical storage of vertices and edges in memory and on disk.
RESTPP	REST++. The high-performance API server that handles all incoming HTTP requests.
gadmin	The command-line utility for managing system configuration, starting/stopping services, and monitoring health.
MultiGraph	A security and multi-tenancy feature that allows multiple logical graphs to exist within one physical cluster.
Accumulator	A specialized GSQL variable type used to store and aggregate values across vertices during a traversal.
Dictionary	The component that stores metadata about the system, including schemas, query definitions, and user roles.
Native Parallel Graph	The core architecture of TigerGraph, where compute is distributed across every vertex and edge.
TigerGraph Cloud	The fully managed Database-as-a-Service (DBaaS) version of the platform.
TigerGraph Savanna	The next-generation cloud platform featuring decoupled compute and storage.

[!NOTE] If you encounter an acronym like IDS (ID Service), it refers to the component within the GSE that maps external IDs (like strings) to internal integer IDs.
