In the Temporal Go SDK programming model, a Workflow Definition is an exportable function.

Create an instance of `ActivityOptions` from the `go.temporal.io/sdk/workflow` package and use `WithActivityOptions()` to apply it to the instance of `workflow.Context`.

First, enable Sessions on the Worker via the Worker Options and then use the `CreateSession` API to create a Context object that can be passed to the calls to spawn Activity Executions.

To customize the Workflow Type set the `Name` parameter with `RegisterOptions` when registering your Workflow with a Worker.

To customize the Workflow Type set the `Name` parameter with `RegisterOptions` when registering your Workflow with a Worker.

A Query type, also called a Query name, is a `string` value.

Develop an instance of a Worker by calling `worker.New()`, available via the `go.temporal.io/sdk/worker` package.

In the Temporal Go SDK programming model, an Activity Definition is an exportable function or `stuct` method.

Emit metrics

Use the SideEffect API from the `go.temporal.io/sdk/workflow` package to execute a Side Effect directly in your Workflow.

Use the Future returned by `ExecuteWorkflow` API call to retrieve the result.

Use the Future returned from the `ExecuteActivity` API call to retrieve the result.

Use the `SetQueryHandler` API to set a Query Handler that listens for a Query by name.

Use, the `RecordHeartbeat` API to report that the execution is alive and progressing.
