Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to recent system changes. Have there been any significant updates or deployments to Palantir Gotham in the past week?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a major update. Impact on approach: If yes, we'd focus on the changes made; if no, we'd look at other factors.

• Considering the scale of the increase, I'm wondering about data volume changes. Has there been a significant increase in data ingestion or user activity recently?

Why it matters: Increased data load could explain performance degradation. Expected answer: Data volume has remained relatively stable. Impact on approach: If volume increased, we'd focus on scaling; if not, we'd look at other factors.

• Given the nature of Gotham, I'm curious about query complexity. Are we seeing this increase across all query types, or is it specific to certain complex queries?

Why it matters: Helps narrow down if it's a general issue or specific to certain operations. Expected answer: The increase is seen across various query types. Impact on approach: If specific, we'd focus on those query types; if general, we'd look at broader system issues.

• Thinking about system health, I'm concerned about potential hardware issues. Have there been any alerts or anomalies in our infrastructure monitoring systems?

Why it matters: Hardware problems can cause widespread performance issues. Expected answer: No significant hardware alerts have been reported. Impact on approach: If hardware issues are present, we'd prioritize infrastructure; if not, we'd focus on software and data aspects.
