What is Generalized Metadata Service (GMS)?

Metadata for entities onboarded to GMA is served through microservices known as Generalized Metadata Service (GMS). GMS typically provides a Rest.li API and must access the metadata using GMA DAOs.

GMA is designed to support a distributed fleet of GMS, each serving a subset of the GMA graph. However, for simplicity we include a single centralized GMS (datahub-gms) that serves all entities.
