Enhancing Cost Management and Usage Tracking in BigQuery
Written on
Chapter 1: Understanding BigQuery Usage
To ensure that your Data Warehouse, Data Lake, or Data Lakehouse does not turn into a Data Swamp, consistent monitoring is essential. It’s vital to manage metrics that govern data usage and to keep an eye on expenses. Whether you are an individual or part of an organization, being vigilant about costs is crucial. Despite the numerous benefits of cloud-based data solutions, expenses can escalate if users frequently access large volumes of data or mishandle the data processing.
Google allows users to transfer logs directly into BigQuery for analysis through SQL. Additionally, tools like Data Studio can be utilized to create comprehensive reports, keeping key stakeholders such as CIOs and CDOs informed about your platform's performance. This practice not only enhances security but also helps mitigate excessive costs.
Logging and Monitoring with BigQuery
Setting up logging for BigQuery is quite straightforward. Within the Logs and Monitoring service, you can ensure that logs are directed into BigQuery, where they can be analyzed like any regular table. For a more detailed guide, refer to the comprehensive tutorial available from Google. Additionally, configuring alerts for when certain thresholds are exceeded can prove beneficial.
What's New in Metrics?
For those already familiar with monitoring and logging, here's a key update: metrics for query/statement_scanned_bytes and query/statement_scanned_bytes_billed are no longer subject to a six-hour delay for smoother job reporting. Instead, these values are now updated every 60 seconds without smoothing. For more insights on metrics, refer to the Google Cloud documentation.
This change in metrics is significant. By reducing the delay on scanned bytes and billed bytes, it enhances the analysis of queries and their execution time. This is particularly relevant for cost management, as the total cost is a product of scanned bytes and their associated price. While this may seem like a minor adjustment, it can lead to significant savings by allowing for quicker responses to avoid unnecessary expenses. The previous delays were frustrating, and a one-minute refresh is much more advantageous.
If you haven't yet implemented any monitoring strategies, I encourage you to explore the available resources. Empower yourself to take charge of your data and expenses effectively.
