“"With Runtime Events, you can target users based on specific Mixpanel events in real time. When a user triggers a designated event, they receive the active variant on the next flag evaluation, without waiting for a cohort refresh."”Claim evidence: source page
What it actually means
Feature flag exposure depends on immediate detection of specific client-side events and the next flag evaluation cycle, requiring flawless event delivery and no backend delays.
How to test it
The Event-to-Flag Latency Test: Track time from event trigger to flag exposure and verify updates in CRM or feature flag dashboards.
▶4 hidden assumptions
- Client-side SDK reliably captures and sends events without delay or loss
- Flag evaluation logic runs frequently enough to reflect real-time events
- User profiles are updated in CRM or internal systems promptly to reflect flag exposure
- No backend cohort refresh needed for these real-time updates
Roast: Claims real-time targeting; reality depends on flawless event capture and zero lag in evaluation cycles.
