What is the primary benefit of the NCache Startup Loader?

The primary benefit of the NCache Startup Loader is the elimination of 'cold cache' performance issues. By preloading essential datasets into memory at startup, applications avoid initial slow response times caused by frequent database trips.

What is the difference between Cache Loader and Cache Refresher?

The Cache Loader is responsible for pre-populating the cache only once when the cache starts. In contrast, the Cache Refresher is an ongoing process that periodically updates that loaded data at user-defined intervals to ensure it remains synchronized with the data source.

Can NCache load datasets in parallel during startup?

Yes. NCache distributes user-defined datasets across different nodes in a cluster using a round-robin algorithm. Each node loads its assigned datasets independently, achieving parallel data ingestion and significantly faster warm-up times.

Cache Loader and Refresher

NCache provides the Cache Startup Loader and Cache Refresher to optimize application warm-up and ensure data consistency. The Cache Startup Loader pre-populates the cache with required application data at cache startup, ensuring that frequently used datasets are readily available as soon as the cache becomes active. This significantly reduces application warm-up time and avoids performance degradation caused by initial cache misses. To ensure data consistency over time, the Cache Refresher periodically updates the preloaded cache data by synchronizing it with the underlying data source based on user-defined refresh intervals. This section describes the implementation and usage of Cache Startup Loader and Refresher.
