Professional social graph

Latest stable Based on Graph release 0.5.1

Problem and backend

This example connects people, employers, skills, and endorsements to exercise several social-graph lookup shapes. It uses TinkerGraph to isolate modeling from container and network variance. Read core model and TinkerPop first; use the selection guide before production.

Model

Nodes: Person/Company/Skill
Edges: KNOWS/WORKS_AT/FOLLOWS/HAS_SKILL/ENDORSES
Key properties: name, title, company, skills, strength, role, level

Prerequisites and release boundary

Use JDK 21, commit 3e0fa7cb9e3bc70c2743aeebda2487f3e45e4907, and the checked-in wrapper. Examples are not published; run this release fixture as a Gradle project from the release source checkout. In a consumer application, select only bluetape4k-dependencies:<ecosystem-version> and add the required graph module without an individual version.

Run and observe

./gradlew :linkedin-graph-examples:test --tests "io.bluetape4k.graph.examples.linkedin.TinkerGraphLinkedInGraphTest"

The tests assert direct connections, a multi-hop connection path, second-degree connections, employer lookup, and follower lookup. A failure identifies which social relation or lookup direction no longer matches the fixture, so inspect that assertion before widening traversal depth.

Reading order

Continue from recommendation, then read iam-access-graph. Also see paired APIs, testing, and operations.

Exercises and production gaps

Add one result-changing edge and assertion; repeat through the suspend API; then run a persistent-backend concrete test serially. Add disconnected and malformed inputs as diagnostics. This fixture does not prove throughput, clustering, authorization, tenant isolation, migration, backup, remote-driver timeout, or index quality.
