You need to create a single report that can be run at different times for different months without editing the stream after it has been deployed. How should you build the stream?

Creating a report that can be run at different times for different months without the need to edit the stream after deployment is best achieved through the use of a session parameter for the month. By defining a session parameter, you enable the flexibility to input the desired month at runtime, which means that when the report is executed, you can simply specify which month you need data for. This approach is dynamic and efficient, as it does not require altering the underlying stream structure or logic each time you want to generate a report for a different month.

When the session parameter is implemented, the report users can input their desired value directly at runtime, allowing the same stream to function effectively for any specific month. This maximizes the reusability of the stream and reduces the potential for errors from manual edits when changing the month of data being reported.

In contrast, other methods such as creating a filler node, hard coding the month, or using a partition node would not provide the same level of flexibility and efficiency. These alternatives could either require manual intervention every time a change is needed or complicate the report generation process unnecessarily.
