Embodiments facilitate efficient and flexible handling of metadata for processing in a microservice architecture (MSA) environment. A consumer service and a provider service both utilize a data model having metadata. A central repository stores metadata information that is being called for by a consumer service. A dedicated meta service manages the metadata repository by listening to a message queue to obtain model-relevant metadata information from a provider service. That model-relevant metadata information may be static in nature, or may be dynamic (e.g., varying as between different tenants). The meta service recognizes the static/dynamic nature of the model-relevant metadata information (e.g., based upon content such as a tenant ID or other information) in a message from the provider service, and stores the metadata accordingly. Once stored in the central repository, the model-relevant metadata information may be communicated directly to the consumer service.
