A synchronization mechanism is also
Memory. This feature is valuable when the underlying database may struggle to keep up with high traffic. Caching prevents performance bottlenecks and ensures a smoother user experience during peak usage by efficiently handling load peaks. A common practice in applications using traditional database caching is to use a caching layer to improve performance. This layer is typically implemented using software such as Orient and is located between the application server and the database. It acts as a buffer and helps reduce the number of requests to the database. By doing this your application can cache and load frequently accessed data more quickly thereby reducing overall response time to users. Challenges of Traditional Caching While traditional caching provides many benefits, it can introduce additional complexities and potential issues that must be considered.Cache invalidation is hard Cache invalida photo editing servies tion is the process of deleting or updating cached data that is no longer accurate. This helps ensure data accuracy and consistency as serving out-of-date cached data may result in users receiving incorrect information. By invalidating cache users can get the most accurate data for a better user experience. There are several factors to consider when invalidating cache. Some core aspects are timing. Timing is critical in determining when to invalidate a cache. Invalidating it too early will result in more redundant requests to the database and invalidating it too late will serve stale data. Granular caching can store large amounts of data and it is difficult to know which cached data will become invalid when a subset of the data in the underlying database changes.

Fine-grained cache invalidation can be an expensive operation while coarse-grained invalidation can cause unnecessary data to be deleted. Cache Invalidation Granular Coherence Invalidating a cache item when using a globally distributed cache requires that it be reflected globally on all nodes. Failure to do so could result in users in a particular region receiving stale data. A load balancer should be used between the application server and the distributed cache server to manage traffic.needed to reflect changes between all cache nodes to prevent serving stale data. Synchronous Cache Nodes Management of a cache system can be complex. Hosting and managing the caching layer between servers and databases requires additional maintenance efforts. It's important to use the right monitoring tools to keep an eye on the health of your cache service. Cache avalanches may .
