Event Volume Limit

An event volume limit is a cap a plan or tool sets on the number of events in a period; exceeding it either adds cost or leads to sampling and dropping.

An event volume limit is more a pricing and capacity matter than an analytical one, but its effect lands directly on data quality. As you approach the cap, the tool's behavior matters: some drop extra events, some sample, and some charge overage; the worst case is blind dropping that sacrifices exactly the rare-but-important events. So teams learn to manage the cap with instrumentation discipline rather than fear: every high-volume, low-value event, such as a scroll event on every scroll, both eats the cap and adds nothing to a decision. A common misconception is that the cap is the same across all data types; in many tools the analytics-event cap differs from the session-recording cap and must be watched separately.
