You are responsible for monitoring your organization’s data lake hosted on BigQuery. The data ingestion pipelines read data from Pub/Sub and then write this data into tables on BigQuery. After deploying a new version of these ingestion pipelines, you notice that the daily stored data in BigQuery has increased by 50%. It is important to note that the volume of data in Pub/Sub has remained constant, and only certain tables have experienced a doubling in the size of their daily partition data. You are tasked with investigating and resolving the cause of this unexpected increase in data storage. What steps should you take to address this issue?
