    • withRemoteDuration

      @NewChain @NotNull default @NotNull CacheCreator withRemoteDuration(@Nullable @Nullable Duration duration)
      Set L2 cache expiration time.

      This method does not modify the current object, but creates a new object.

      Note: This method is equivalent to withRemoteDuration(duration, 30)

      参数:
      duration - The expiration time
      返回:
      The created new object

    • withRemoteDuration

      @NewChain @NotNull @NotNull CacheCreator withRemoteDuration(@Nullable @Nullable Duration duration, int randomPercent)
      Set L2 cache expiration time.

      This method does not modify the current object, but creates a new object.

      参数:
      duration - The expiration time
      randomPercent - A random percent

      Batch loading is a frequently used optimization method in jimmer, so a batch of values are often put into the cache at the same time. If the expiration time of these cached data is the same, then in the future, some affected data will be discarded by the cache at the same time so that a big hole will appear in the defense of the cache, which is easy to be penetrated.

      To solve this problem, Jimmer supports a random factor that modifies the expiration time and then applies it to the L2 cache, ultimately making the expiration time of the data uneven.

      返回:
      The created new object
