A federated graph router resolves sharded objects across distributed subgraph instances by first fetching shard-discovery metadata, then routing fetch operations to the correct instance.

Patentradars sammanfattning

This invention describes a method and system for querying sharded data objects within a federated supergraph architecture. A router receives a client query for objects that may be distributed (sharded) across multiple subgraph instances, generates a query plan comprising at least two sequential operations: a first operation retrieves shard discovery information (e.g., binding metadata mapping object IDs to specific instance FQDNs), and a second operation uses that metadata to identify and directly fetch the sharded objects from the correct subgraph instances. The approach is particularly suited to telecom network function environments (e.g., 5G PCF bindings) where session data is partitioned across many service instances.
