Hi,
I'm currently investigating the evitction policies available in Infinispan and have noticed some unexpected(?) functionality in regards to setting maxEntries.
If i set maxEntries to 10, and then add 10 entries to the cache only 7 of them will remain in the cache, with 3 apparently being evicted. I would expect for all 10 to remain in the cache... The code for this basic test is below (I have tried with a configuration xml as well and have had the same results)
public static void main(String[] args) throws Exception {
EmbeddedCacheManager manager = new DefaultCacheManager();
manager.defineConfiguration("eviction-cache", new ConfigurationBuilder()
.eviction().strategy(EvictionStrategy.LIRS).maxEntries(10)
.build());
Cache<Object, Object> evictionC = manager.getCache("eviction-cache");
int counter = 0;
while (counter < 10) {
evictionC.put("key" + counter, "" + counter);
counter++;
}
System.out.println(evictionC.size());
System.out.println(evictionC.values());
}
This results in the following being output into the console:
7 (size)
[9, 8, 7, 4, 0, 5, 3] (values)
Any help with this would be appreciated.
Thanks,
Brent
