Cache Size
Noun · Development
Definitions
The amount of memory or storage allocated to a cache for holding entries. Cache size is a key tuning parameter because too little space causes churn and low hit rates, while too much can waste memory or hurt locality and eviction behavior.
In plain English: How much space is available for a cache to store items.
Example: "They increased cache size for the product index because the working set no longer fit after adding region-specific pricing and inventory variants."
