Metastore services are fully managed, highly available, auto-scaled, auto-healing, OSS-native deployments of technical metadata management software. Each metastore service exposes a network endpoint through which metadata queries are served. Metadata queries can originate from a variety of sources, including Apache Hive, Apache Presto, and Apache Spark.
The Dataproc Metastore API defines the following resource model:
The service works with a collection of Google Cloud projects, named:
/projects/*Each project has a collection of available locations, named:
/locations/*(a location must refer to a Google Cloudregion)Each location has a collection of services, named:
/services/*Dataproc Metastore services are resources with names of the form:
/projects/{project_number}/locations/{location_id}/services/{service_id}.
