"Caching" refers to the process of temporarily storing data in a faster accessible memory to accelerate access to that data and improve performance. Frequently accessed data or resources are cached to make repeated accesses faster and reduce the load on the primary storage or database.
Typical functions of software in the "Caching" domain are:
Data caching: The software stores frequently accessed data or resources in a cache to speed up access to them.
Automatic updating: It automatically updates the cache when the data in the underlying data source changes to ensure that the cached data is current.
Cache expiration control: The software manages the lifecycle of data stored in the cache and automatically removes outdated or no longer needed entries to free up space.
Cache policy management: It allows for the configuration of cache policies to specify how long data should be stored in the cache and under what conditions it should be updated or removed.
Support for different cache types: The software provides support for different types of caches, including memory caches, database caches, HTTP caches, and others, to cover different requirements and scenarios.
Scalability and performance optimization: It optimizes the performance and scalability of applications by reducing the load on databases or other slow data sources and improving response times for users.
Error handling and fault tolerance: The software includes mechanisms for detecting and handling errors in the cache to prevent failures or data inconsistencies and ensure the availability of the application.
