Improvements to GA4 Data Sampling and Table Selection

Enhancements have been made to data sampling and the selection of tables in Google Analytics. The platform now utilises two types of tables optimised for either performance or flexibility when storing data from your website or app. With this update, Google Analytics dynamically selects the table that best suits each query, thereby minimising the likelihood of encountering the (other) row and experiencing data sampling in reports and explorations.

Consequently, in explorations or reports involving data sampling, you may now observe the (other) row. This selects the table based on your query to deliver the most precise results and mitigate the impact of data sampling and cardinality limits.
