BigQuery is designed to scale to petabytes of data and efficiently retrieve that data using a full range of SQL queries but things do not always go as planned. Queries may take too long to execute or fail because of insufficient resources. Without an understanding of BigQuery architecture and how to find details about errors it can be difficult to troubleshoot errors. Review on how BigQuery allocates resources and discussion how to use execution details, logs, and information_schema data to analyze errors in BigQuery is in this presentation. Look into data modeling and ingestion best practices that can help minimize performance problems.
