Google.Cloud.DataCatalog.V1 is a.NET client library for the Data Catalog API.
Note:
This documentation is for version 2.8.0 of the library.
Some samples may not work with other versions.
Installation
Install the Google.Cloud.DataCatalog.V1 package from NuGet. Add it to
your project in the normal way (for example by right-clicking on the
project in Visual Studio and choosing "Manage NuGet Packages...").
Authentication
When running on Google Cloud, no action needs to be taken to authenticate.
Otherwise, the simplest way of authenticating your API calls is to
set up Application Default Credentials.
The credentials will automatically be used to authenticate. See
Set up Application Default Credentials for more details.
Getting started
All operations are performed through the following client classes:
Create a client instance by calling the static Create or CreateAsync methods. Alternatively,
use the builder class associated with each client class (e.g. DataCatalogClientBuilder for DataCatalogClient)
as an easy way of specifying custom credentials, settings, or a custom endpoint. Clients are thread-safe,
and we recommend using a single instance across your entire application unless you have a particular need
to configure multiple client objects separately.
Using the REST (HTTP/1.1) transport
This library defaults to performing RPCs using gRPC using the binary Protocol Buffer wire format.
However, it also supports HTTP/1.1 and JSON, for situations where gRPC doesn't work as desired. (This is typically due to an incompatible proxy
or other network issue.) To create a client using HTTP/1.1, specify a RestGrpcAdapter reference for the GrpcAdapter property in the client builder.
Sample code:
var client = new DataCatalogClientBuilder
{
GrpcAdapter = RestGrpcAdapter.Default
}.Build();
