# Experiments: No Refresh with variable TTL
|
||||
|
||||
Explanation for files in each experiment:
|
||||
|
||||
- `details.csv`: Access Count, Hit, Miss, Mu, Lambda and Hit Rate for each object
|
||||
- `hit_age.csv`: Shows hit rate/average age at time of request for each object.
|
||||
- `lambda_distribution.pdf`: Lambda Distribution across all objects/discrete
|
||||
values of the Zipf distribution
|
||||
- `lambda_vs_access_count.pdf`: Displays the access count against lambda,
|
||||
expecting a higher lambda to result in a higher access count.
|
||||
- `objects_in_cache_over_time.pdf`: Amount of cache entries at given time.
|
||||
- `overall_hit_age.csv`: Cumulative description of `hit_age.csv`
|
||||
|
||||
Length of simulation doesn't change much since we're not touching the request
|
||||
rate across the simulations.
|
||||
Break condition for the simulation is when the each database object has been
|
||||
requested at least `ACCESS_COUNT_LIMIT` (i.e. 10) times.
