Ads Group, Ads Measurement Platform Team Automated View Optimization for Databasebuild a tool that uses historical data to generate optimized views that are more performant than existing views in database. View level: Given query and view, this tool estimates how performant this view will do for the query relative to current existing view in database. Use case level: Given use case and acceptable capacity increase, this tool recommends best views with expected performance gains. It samples historical queries from the use case and generates a number of query shapes with most expensive rows read. The tool then creates a fixed number of views that cover query shapes with most expensive total rows read.
