This script runs simulations to analyze cache hit rates under different configurations.
It varies:
- Number of scenes requested per request
- Cache expiration time
For each combination, it simulates cache requests and counts the number of "cold storage hits". This represents when a request cannot be served from cache and must fetch from cold storage.
The hit rate is calculated as:
cold_storage_hits / number_of_requests
Results are saved to results.csv including:
- Number of requests
- Cache expiration
- Scenes per request
- Cold storage hits
- Hit rate
Rows are sorted by highest to lowest hit rate.
This allows analyzing which factors increase the cache hit rate and reduce trips to slow cold storage.
