Scenario: You are monitoring your organization's data lake hosted on BigQuery. The ingestion pipelines read data from Pub/Sub and write the data into tables on BigQuery. After deploying a new version of the ingestion pipelines, the daily stored data increased by 50%. The volumes of data in Pub/Sub remained the same and only some tables had their daily partition data size doubled. You need to investigate and resolve the cause of the data increase. Question: What should you do to investigate and fix the cause of the data increase?
