Introduction

Balancing increased data retention periods with system performance and costs is a critical challenge for Datadog. This trade-off involves extending the timeframe for storing customer data while managing the impact on system resources and operational expenses. I'll analyze this scenario using a structured approach, considering technical, business, and user perspectives.

Analysis Approach

I'd like to outline my approach to ensure we're aligned on the key areas I'll be covering in my analysis.

Step 1

Clarifying Questions (3 minutes)

Context: I'm assuming this is driven by customer demand for longer-term analytics. Could you confirm if this is a proactive initiative or a response to specific customer requests?

Why it matters: Helps prioritize the urgency and scope of the solution. Expected answer: Mix of both, with increasing customer requests. Impact on approach: Would influence the balance between immediate implementation and phased rollout.

Business Context: Based on Datadog's subscription model, I'm thinking this could impact our pricing tiers. How does this align with our current pricing strategy and revenue goals?

Why it matters: Determines if we need to adjust our pricing model alongside the technical changes. Expected answer: Potential for new premium tiers or add-on services. Impact on approach: Would require coordination with sales and marketing for potential pricing adjustments.

User Impact: I'm considering the different use cases for extended data retention. Can you share insights on which customer segments are most interested in longer retention periods?

Why it matters: Helps tailor the solution to specific user needs and prioritize implementation. Expected answer: Enterprise clients in regulated industries are primary drivers. Impact on approach: Would focus on compliance and regulatory features in the initial phases.

Technical Feasibility: Given our current architecture, I'm curious about the main technical bottlenecks for extending retention. What are our primary constraints – storage, processing power, or data retrieval speed?

Why it matters: Identifies the core technical challenges to address. Expected answer: A combination, with storage being the primary concern. Impact on approach: Would prioritize storage optimization and tiered data access strategies.

Resource Allocation: Considering the potential scope, I'm thinking this might require significant engineering effort. What's our current team capacity and budget allocation for this initiative?

Why it matters: Determines the scale and timeline of the implementation. Expected answer: Moderate resources available, competing with other priorities. Impact on approach: Would suggest a phased approach, starting with high-impact, low-effort improvements.
