microservice cache strategy

Wirelessly's cache consists of two scenarios, memory cache and disk cache, where the memory cache is primarily using the LRUCache class, where the memory cache I have already explained in detail in the memory cache LRUCache of the

work system.Today, I will understand how the Http cache header works together from a system-based perspective (incorrect place, please correct me, but please do not spray me):HTTP Cache ArchitectureFirst I will divide the Http caching system into the following three parts:1. Cache Storage PoliciesUsed to determine whether the Http response content can be cached

not that the browser is no longer caching data, but the browser is using the slowWhen you save the data, you need to make sure that the data is still consistent with the server. If No-cache is set, and the ETag implementation does not reflect a change in resources, itCauses the browser's cached data to be kept from being updated.No-storeIf the server is set to No-store or Cache-control:no-store in the resp

expire after 1 days. You can combine ETag, Cache-control, and unique URLs to achieve a single swoop: longer expiration, control over where the response can be cached, and on-demand updates.Cache Check List There is no best caching policy. You need to define and configure the appropriate settings for each resource, as well as the overall cache hierarchy, based on the communication pattern, the ty

On MySQL InnoDB cache policy:The InnoDB Buffer PoolInnodb holds a storage area called buffer pool to cache data and indexes in memory, knowing how Innodb Bufferpool works, and using it to read frequently accessed data, is an important aspect of MySQL optimization.Ideally, adjust the size of the bufferpool to large enough to leave enough memory space for other processes on the server (so that it has no missi

between the call is very fast. This deployment is ideal for caching class data and is less sensitive to cross room calls. In this case, if a computer room down machine, that the machine corresponding data will be lost, but the problem is not very small, because it is cached data, can continue from the persistence of the system inside to load in. Since it is a single piece of data, there is no question of consistency. machine distributed in a number of computer rooms, a data room, for the extern
