In your role as a data engineer, you are managing a real-time data processing pipeline using Google Cloud Dataflow. This pipeline is designed to receive messages from a Google Cloud Pub/Sub topic and subsequently write the processed data to a BigQuery dataset located in the European Union. Currently, the Dataflow pipeline is hosted in the europe-west4 region and operates with a maximum of 3 worker instances, each of type n1-standard-1. Recently, you have observed that during periods of high data inflow, the pipeline struggles with processing records promptly, as all three worker instances reach maximum CPU utilization.
