%description
|
||
|
|
Cachey tries to hold on to values that have the following characteristics
|
||
|
|
|
||
|
|
1. Expensive to recompute (in seconds)
|
||
|
|
2. Cheap to store (in bytes)
|
||
|
|
3. Frequently used
|
||
|
|
4. Recenty used
|
||
|
|
|
||
|
|
It accomplishes this by adding the following to each items score on each access
|
||
|
|
|
||
|
|
score += compute_time / num_bytes * (1 + eps) ** tick_time
|
||
|
|
|
||
|
|
For some small value of epsilon (which determines the memory halflife.) This
|
||
|
|
has units of inverse bandwidth, has exponential decay of old results and
|
||
|
|
roughly linear amplification of repeated results.
