Introduction

TuGraph Analytics (alias: GeaFlow) is the fastest open-source OLAP graph database developed by Ant Group. It supports core capabilities such as trillion-level graph storage, hybrid graph and table processing, real-time graph computation, and interactive graph analysis. Currently, it is widely used in scenarios such as data warehousing acceleration, financial risk control, knowledge graph, and social networks.

Development Manual

GeaFlow supports two sets of programming interfaces: DSL and API. You can develop streaming graph computing jobs using GeaFlow's SQL extension language SQL+ISO/GQL or use GeaFlow's high-level API programming interface to develop applications in Java. * DSL application development: DSL Application Development * API application development: API Application Development

Real-time Capabilities

Compared with traditional stream processing engines such as Flink and Storm, which use tables as their data model for real-time processing, GeaFlow's graph-based data model has significant performance advantages when handling join relationship operations, especially complex multi-hops relationship operations like those involving 3 or more hops of join and complex loop searches.

total_time

Why using graphs for relational operations is more appealing than table joins?

Association Analysis Demo Based on GQL:

--GQL Style
Match (s:student)-[sc:selectCource]->(c:cource)
Return c.name
;

Association Analysis Demo Based on SQL:

--SQL Style
SELECT c.name
FROM course c JOIN selectCourse sc 
ON c.id = sc.targetId
JOIN student s ON sc.srcId = s.id
;
