Refresh-ahead
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 of refresh-ahead:
- Not accurately predicting which items are likely to be needed in the future can result in reduced performance than without refresh-ahead.
