Flushing the shared pool should do it, but Tom Kyte lists a couple reasons below why you may not get the result you are expecting in some cases: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:6349391411093
I realize this question is old, but in the interest of helping anyone who finds this via search, its worth noting that .net v4 includes a new general purpose cache for this type of scenario. It’s in the System.Runtime.Caching namespace: https://msdn.microsoft.com/en-us/library/dd997357(v=vs.110).aspx The static reference to the default cache instance is: MemoryCache.Default
From HTTP Header Field Definitions: 14.9.3 Modifications of the Basic Expiration Mechanism … s-maxage If a response includes an s-maxage directive, then for a shared cache (but not for a private cache), the maximum age specified by this directive overrides the maximum age specified by either the max-age directive or the Expires header. … Note, … Read more
If you are using .NET 4 or superior, you can use MemoryCache class.
Ok, so, in order to use caching for your queryset: class ProductListAPIView(generics.ListAPIView): def get_queryset(self): return get_myobj() serializer_class = ProductSerializer You’d probably want to set a timeout on the cache set though (like 60 seconds): cache.set(cache_key, result, 60) If you want to cache the whole view: from django.utils.decorators import method_decorator from django.views.decorators.cache import cache_page class ProductListAPIView(generics.ListAPIView): … Read more
The static middleware does no server-side caching. It lets you do two methods of client-side caching: ETag and Max-Age: If the browser sees the ETag with the page, it will cache it. The next time the browser loads the page it checks for the ETag number changes. If the file is exactly the same, and … Read more
You can use LinkedHashMap like this You can remove by LRU or FIFO. public static <K, V> Map<K, V> createLRUMap(final int maxEntries) { return new LinkedHashMap<K, V>(maxEntries*10/7, 0.7f, true) { @Override protected boolean removeEldestEntry(Map.Entry<K, V> eldest) { return size() > maxEntries; } }; }
We tested both and found Enyim to perform the best for our expected usage scenario: many (but not millions) cached objects, and millions of cache-get requests (average web site concurrency load = 16-20 requests.) Our performance factor was measuring the time from making the request to having the object initialized in memory on the calling … Read more
