Hi Folks,
Pardon the somewhat basic question, I did try going through various online
guides but never really got the answer to this one.
I am running app-engine with 3 instances. I share data across these
instances using Memcache. What is the right way to instantiate it such that
all three appengine instances end up writing to the same cache?
Here is the code that I used:
public static synchronized <K, V> Map<K, V> createMemcache(
String cacheName, ReadableDuration inactivityTimeout, @Nullable
CacheListener cacheListener) {
try {
CacheManager cacheMgr = CacheManager.getInstance();
Cache cache = cacheMgr.getCache(cacheName);
if (cache == null) {
CacheFactory cacheFactory = cacheMgr.getCacheFactory();
ImmutableMap<String,Long> env =
ImmutableMap.of(GCacheFactory.EXPIRATION_DELTA_MILLIS,
inactivityTimeout.getMillis());
cache = cacheFactory.createCache(env);
if (cacheListener != null) {
cache.addListener(cacheListener);
}
cacheMgr.registerCache(cacheName, cache);
}
return cache;
} catch (CacheException e) {
}
Any comments? Will this create the shared Memcache as I want it?
Thanks
Inder
