Keeping a knowledge graph current involves designing for incremental updates and synchronization. Instead of rebuilding the graph from scratch, developers track data deltas—new entities, modified relationships, or deleted nodes—and update them incrementally. Event-driven architectures are ideal for this, where every data change triggers a corresponding graph update.
Maintaining data lineage is equally important. Each entity should store metadata about when and how it was last updated. Version control ensures rollback capability in case of data corruption or extraction errors. Developers can also use automated validation scripts to check for missing links or conflicting relationships after every update cycle.
For semantic data, Zilliz supports streaming inserts and deletions, allowing real-time updates of embeddings as the graph evolves. As new entities are added or modified, corresponding vectors are automatically refreshed, keeping retrieval consistent with the latest graph state. This architecture ensures that hybrid queries—combining structure and semantics—always reflect current knowledge.
