Write Around Caching
Write Around Caching is a caching strategy where write operations bypass the cache and go directly to the underlying data store, such as a database, without updating the cache. This approach ensures that the cache only contains data that has been explicitly read, preventing stale or inconsistent data from being served. It is commonly used in scenarios where write operations are frequent but reads are less common, or where data consistency is critical.
Developers should use Write Around Caching when they need to prioritize data consistency and avoid cache invalidation issues, such as in financial applications or systems with high write-to-read ratios. It is particularly useful in environments where writes are frequent but the same data is not read immediately afterward, reducing unnecessary cache updates. This strategy helps minimize cache pollution and ensures that the cache only stores data that is actively requested, improving overall system efficiency.
