A data engineer is working on a Structured Streaming job within Databricks. The job reads data from an existing table, processes the data, and then writes the output to a new table in a streaming fashion. The data engineer aims to configure the streaming job so that it processes the data in micro-batches with a frequency of every 5 seconds.

Given the code block used by the data engineer, which line of code should be used to accomplish this 5-second micro-batch interval requirement?
