Data Catalog offers several programmatic interfaces for
interaction, and we recommend using them in the following order:
Google Cloud Client Libraries:
Data Catalog client libraries are available in multiple
languages and are built on gRPC. These client libraries
provide a layer of abstraction on top of gRPC and handle the details of
operation polling and retries. For more information, see
Data Catalog client libraries.
gRPC: If your preferred programming
language lacks a dedicated client library, you can still generate gRPC client
libraries for Data Catalog using any gRPC-supported language.
This requires the
protocol buffers
service definition, which is available in the
GitHub repository.
To generate and use your client, refer to the instructions on
grpc.io for your chosen language.
REST API: if you're unable
to use Data Catalog's client libraries or the gRPC API, use the
REST API.
