TigerVector: Supporting Vector Search in Graph Databases for Advanced RAGs Open
In this paper, we introduce TigerVector, a system that integrates vector search and graph query within TigerGraph, a Massively Parallel Processing (MPP) native graph database. We extend the vertex attribute type with the embedding type. To…

In-Memory Object Graph Stores Open
We present a design and implementation of an in-memory object graph store, dubbed εStore. Our key innovation is a storage model - epsilon store - that equates an object on the heap to a node in a graph store. Thus any object on the heap (w…

Chasing Parallelism in Aggregating Graph Queries Open
In practice, one frequently encounters queries that extract tabular results from graph databases by employing grouping and aggregation. This paper introduces a technique for rewriting the group-by list of graph queries in order to increase…

The Linked Data Benchmark Council (LDBC): Driving competition and collaboration in the graph data management space Open
Graph data management is instrumental for several use cases such as recommendation, root cause analysis, financial fraud detection, and enterprise knowledge representation. Efficiently supporting these use cases yields a number of unique r…

PG-Schema: Schemas for Property Graphs Open
Property graphs have reached a high level of maturity, witnessed by multiple robust graph database systems as well as the ongoing ISO standardization effort aiming at creating a new standard Graph Query Language (GQL). Yet, despite documen…

Connecting The Dots To Combat Collective Fraud Open
Modern fraudsters write malicious programs to coordinate a group of accounts to commit collective fraud for illegal profits in online platforms. These programs have access to a set of finite resources - a set of IPs, devices, and accounts …

Aggregation Support for Modern Graph Analytics in TigerGraph Open
We describe how GSQL, TigerGraph's graph query language, supports the specification of aggregation in graph analytics. GSQL makes several unique design decisions with respect to both the expressive power and the evaluation complexity of th…

Supplementary Material for: Interleukin-27 Ameliorates Renal Ischemia-Reperfusion Injury through Signal Transducers and Activators of Transcription 3 Signaling Pathway Open
Background: Acute kidney injury (AKI) is a clinical syndrome characterized by significant morbidity and a high death rate. Interleukin (IL)-27 is a newly described member of the IL-6/IL-12 heterodimeric cytokine family and displays anti-in…

Property Graph Type System and Data Definition Language Open
Property graph manages data by vertices and edges. Each vertex and edge can have a property map, storing ad hoc attribute and its value. Label can be attached to vertices and edges to group them. While this schema-less methodology is very …
