How should you define the parameters of your compute function to inject a TransformContext?

To inject a TransformContext into a compute function, the parameters must be defined in a way that the context is positioned correctly for access during the execution of the function. In this case, defining the compute function as def compute(ctx, input, output): allows the TransformContext to be the first parameter, followed by the input and output parameters.

The TransformContext holds important information about the execution environment, including configuration details, state, and other contextual information necessary for processing data. By placing this context as the first parameter, it becomes intuitive to access and manipulate within the compute function. This is crucial for optimizing the data transformation process, as it ensures that the context is readily available for any necessary operations, such as logging, configuration retrieval, or managing dependencies.

In the other options, the placement or inclusion of the TransformContext does not conform to the expected signature needed for the context injection. Thus, defining the function as stated is the correct approach.
