caching

问题 I am trying to enable Hibernate's 2nd level cache but cannot avoid multiple queries being issued for OneToOne relations. My models are: @Entity @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Business { @OneToOne(mappedBy = "business", cascade = {CascadeType.REMOVE}, fetch = FetchType.EAGER) private Address address; } @Entity @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Address { @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name = "business_id", unique

问题 So I have some items stored in Rails.cache and I always write them with :expires_in => 5.minutes My question is, is there a way to see what the ttl is on a cache entry? I know the entry class in activesupport has a method but I can't seem to get an entry object out of Rails.cache methods. I'm implementing rate limiting by the way. 回答1: You can check ttl in Rails cache using command below. Rails.cache.data.ttl("yourkey") 来源： https://stackoverflow.com/questions/24896449/checking-ttl-for-rails

问题 I am trying to implement Buildkit's cache mount feature. My Dockerfile is: # syntax = docker/dockerfile:experimental FROM python:3.6-alpine RUN --mount=type=cache,target=/root/.cache/pip pip install pyyaml CMD: docker build --progress=plain -t abc:1 . --no-cache First Run Output: #2 [internal] load .dockerignore #2 transferring context: 2B done #2 DONE 0.0s #1 [internal] load build definition from Dockerfile #1 transferring dockerfile: 175B done #1 DONE 0.0s #3 resolve image config for docker

问题 Somewhere in my app I use Rails.cache.write 'some_key', 'some_value', expires_in: 1.week In another part of my app I want to figure out how much time it is left for that cache item. How do I do that? 回答1: Wow. I just came here looking for this. What a shame the answer is no. My solution, then, which I'm not a fan of, is to cache the expiration as well. Rails.cache.write 'some_key', ['some_value', 1.week.from_now], expires_in: 1.week I suppose it's not the end of the world, except that you

问题 I'm configuring the caching on AWS API Gateway side to improve performance of my REST API. The endpoint I'm trying to configure is using a query parameter. I already enabled caching on AWS API Gateway side but unfortunately had to find out that it's ignoring the query parameters when building the cache key. For instance, when I make first GET call with query parameter "test1" GET https://2kdslm234ds9.execute-api.us-east-1.amazonaws.com/api/test?search=test1 Response for this call is saved in

问题 First, I found some resources online here and here saying about the same thing: For a normal/soft reload, the browser will re-validate the cache, checking to see if the files are modified. I tested it on Chrome. I have a webpage index.html which loads a few javascript files in the end of body . When hitting the refresh button (soft/normal), from the network panel I saw index.html was 304 Not Modified , which was good. However, all the javascript files were loaded from memory cache with status

问题 I'm trying to add caching to a CRUD app, I started doing something like this: @Cacheable("users") List<User> list() { return userRepository.findAll() } @CachePut(value = "users", key = "#user.id") void create(User user) { userRepository.create(user) } @CachePut(value = "users", key = "#user.id") void update(User user) { userRepository.update(user) } @CacheEvict(value = "users", key = "#user.id") void delete(User user) { userRepository.delete(user) } The problem I have is that I would like

问题 Is there a way to tell curl command not to use server's side cache? e.g; I have this curl command: curl -v www.example.com how can I ask curl to send a fresh request to not use the cache? Note : I am looking for an executable command in the terminal. 回答1: I know this is an older question, but I wanted to post an answer for users with the same question: curl -H 'Cache-Control: no-cache' http://www.example.com This curl command servers in its header request to return non-cached data from the
