The Go SDK for Azure Cosmos DB is built on top of the core Azure Go SDK package, which implements several patterns that are applied throughout the SDK. The core SDK is designed to be quite customizable, and its configurations can be applied with the ClientOptions struct when creating a new Cosmos DB client object using NewClient (and other similar functions).

If you peek inside the azcore.ClientOptions struct, you will notice that it has many options for configuring the HTTP client, retry policies, timeouts, and other settings. In this blog, we will cover how to make use of (and extend) these common options when building applications with the Go SDK for Cosmos DB.
