caching

问题 I am stuck in a scenario. My code is like below : Update : its not about how to use data cache, i am already using it and its working , its about expanding it so the method don't make call between the time of expiry and getting new data from external source object = (string)this.GetDataFromCache(cache, cacheKey); if(String.IsNullOrEmpty(object)) { // get the data. It takes 100ms SetDataIntoCache(cache, cacheKey, object, DateTime.Now.AddMilliseconds(500)); } So user hit the cache and get data

问题 I am quite new to react React workbox. I am trying to make my Electron react App have the ability to cache all images and data to be made available while it is offline. This is exactly what I am trying to accomplish as in this youtube video. from 14:00 to 21:00 minutes: Building PWAs with React and Workbox, /watch?v=Ok2r1M1jM_M But this command is giving "start-sw":"workbox injectManifest workbox-config.js && workbox copylibraries build/ && http-server build/ -c 0" This error: C:\Users\rajesh

问题 Okay, I'm currently planning on using Redis as a front end cache to my NoSQL database. I will be storing a lot of frequently used user data in the Redis database. I was wondering if making a key-value entry for each user would be better or using the Redis hash where the field is the user id and the value is a large json object . What do you think would be better? I saw this article to sort of answer the question, but it doesn't discuss the limitations on value size. 回答1: Choosing hash over

问题 I developed a method that use @Cacheable annotation. The code is: @Cacheable(value="reporties" , key="{#root.methodName,#manager.name}") public List<Employee> getReportiesForManager(Employee manager){ // code to fetch reporties its a Spring JDBC call } Now, I want to evict this cache after some events: Some reporties related with manager have been updated (added or removed). After that, the cache related with the manager should be evicted, in that way, the application will get new data

问题 We build a flutter web app and deployed it via firebase hosting. Unfortunately, we didnt configure any caching settings in our initial deploy. Now we deployed a newer version of our website but people still get the old website shown form the first deploy. What we tried so far: Adding version no. to our index.html: <"script src="main.dart.js?version=1" type="application/javascript"></script> Adding meta Data in our header in index.html: <meta http-equiv="Cache-Control" content="no-cache, no

问题 I am attempting to implement caching in my application using Ehcache and the Spring 3.1 built in caching annotations (@Cacheable, @CacheEvict, and @CachePut). I have created a cache as follows: @Cacheable(value = "userCache", key = "#user.id") public List<User> getAllUsers() { ... } I am attempting to update this cache with a new value using the @CachePut annotation as below: @CachePut(value = "userCache", key = "#user.id") public void addUser(User user) { ... } However, the new "User" is not

问题 I am not sure, but if i remember right intel uses a VIPT cache, i would like to know the reason of this choice, why is it better than VIVT or PIPT, what advantages does it procure and maybe what disadvantages. Thank you. 回答1: The exact design decisions are probably not published, but in general the benefits for VIPT are : Virtual indexing means you can start reading the set from the cache before (or in parallel with) looking up the translation in the TLB. This means that the common case
