Within the audit logs you can find BigQueryAuditMetadata details in the protoPayload.metadataJson submessage in the Cloud Logging LogEntry message. GCP has offered several versions of BigQuery audit logs so there are both older “v1” and newer “v2” versions. The v1 logs report API invocations and live within the protoPayload.serviceData submessage while the v2 logs report resource interactions like which tables were read from and written to by a given query or which tables expired. The v2 data lives in a new field formatted as a JSON blob within the BigQueryAuditMetadata detail inside the protoPayload.metadataJson submessage. In v2 logs the older protoPayload.serviceData submessage does exist for backwards compatibility but the information is not set or used. We scrape details from the JobChange object instead. We referenced the GCP bigquery-utils Git repo for how to use INFORMATION_SCHEMA queries and audit logs queries.

If you've ever wondered what it's like to manage a BigQuery instance at Reddit scale, know that it's exactly like smaller systems just with much, much bigger numbers in the logs. Database management fundamentals are eerily similar regardless of scale or platform; BigQuery handles just about anything we throw at it, and we do indeed throw it the whole book. Our BigQuery platform is more than 100 petabytes of data that supports data science, machine learning, and analytics workloads that drive experiments, analytics, advertising, revenue, safety, and more. As Reddit grew, so did the workload velocity and complexity within BigQuery and thus the need for more elegant and fine-tuned workload management.
