Framework

Are query patterns causing excessive compute?

Are sequential lookups and N+1 queries present?

Slow query log: 22% of queries are N+1 with avg 15 sub-queries per parent

Eliminating N+1 with batch loading reduces DB CPU from 68% to 41%

Is denormalization opportunity being missed?

User engagement aggregate refreshed hourly via 12 JOINs: 18% of read traffic

Materialized view with hourly refresh: 8% cost of current JOINs

Is the replication strategy suboptimal?

Is synchronous replication creating write bottleneck?

Writes replicate to 3 regions synchronously: p99 write latency 840ms

Async replication with consistency quorum: p99 latency 85ms, same durability

Are read replicas over-provisioned?

12 read replicas, but 8 carry <5% of read traffic

Consolidating cold replicas to on-demand snapshots saves 60% of replica costs

Is the data model creating unnecessary hot paths?

Are wide columns forcing full row scans?

Profile column holds 4MB of JSON, accessed in <1% of queries

Moving blob to separate table reduces primary key cache footprint by 31%

Are leaderboard / global counters creating lock contention?

Single global counters table: 47% of database lock wait time
