+S1 and S2 SKU ingress rates and capacities provide flexibility when configuring a new Time Series Insights environment. Your SKU capacity indicates your daily ingress rate based on number of events or bytes stored, whichever comes first. Note that ingress is measured *per minute*, and **throttling** is applied using the token bucket algorithm. Ingress is measured in 1-KB blocks. For example a 0.8-KB actual event would be measured as one event, and a 2.6-KB event is counted as three events.
