Final Answer:
The retained RUM data for Waterfall analysis is typically stored for c) 90 days.
Explanation:
RUM (Real User Monitoring) data retention for Waterfall analysis is generally set at 90 days. This duration allows for a comprehensive analysis of user behavior, performance metrics, and website/application insights. Retaining data for this period enables a thorough examination of trends, patterns, and potential issues that might affect user experience or system performance. This timeframe strikes a balance between maintaining valuable data for analysis and managing storage resources efficiently.
RUM data retention period is crucial in understanding long-term trends and performance metrics. It's calculated based on the need for historical data to conduct meaningful analysis while considering storage constraints and the relevance of older data. For instance, a shorter retention period might limit the ability to identify subtle but impactful trends, while an excessively long period could strain storage resources without providing additional analytical benefits. The 90-day duration strikes a balance, allowing enough data for in-depth analysis without overwhelming storage capacities.
This 90-day retention period aligns with industry standards and best practices. It facilitates comprehensive Waterfall analysis by providing a substantial dataset without burdening systems with unnecessary older data. Moreover, it ensures that insights drawn from the analysis remain relevant and actionable, as data beyond this timeframe might lose its relevance or become less valuable for decision-making processes.
