Refresh-ahead
Introduction
Source: From cache to in-memory data grid
You can configure the cache to automatically refresh any recently accessed cache entry prior to its expiration.
Refresh-ahead can result in reduced latency vs read-through if the cache can accurately predict which items are likely to be needed in the future.
Disadvantage(s) : refresh-ahead
- Not accurately predicting which items are likely to be needed in the future can result in reduced performance than without refresh-ahead.
