Framework

Is time complexity the bottleneck?

Are you sorting more times than necessary?

Current: O(n log n) sort on all 50M events

With heap: O(n log k) where k=top 100 events, 2.1s vs 12s

Are lookups in the query linear scan?

Linear scan of 50M events per request: 400ms per query

Hash table index: 2ms lookup, trade 8GB memory vs 400ms latency

Is space complexity acceptable?

Is caching missing intermediate results?

Recalculate top 100 for every region: 8 regions × 50M events

Materialized view with 10-minute TTL: 800 cached results, 95% hit rate

Are data structures bloated?

Full event object in memory: 2KB per event × 50M = 100GB footprint

Store only ID + timestamp: 48 bytes per event = 2.4GB, sorted index

Are there correctness gaps for edge cases?

Does the algorithm handle deleted events?

Naive: delete event from timeline, breaks iteration on live reads (race)

Soft delete with version vector: O(1) mark, consistency preserved

Are concurrent writes handled?

Two threads insert same event ID: duplicate in result
