Hi Lin,
An expiry policy is working for all values, which were added through
cacheWithExpiryPolicy according to the next example:
IgniteCache<Object, Object> cacheWithExpiryPolicy = cache.withExpiryPolicy(
new CreatedExpiryPolicy(new Duration(TimeUnit.SECONDS, 5)));
You are welcome to find an explaining example in the end of this message.
It is also possible, that actually you are looking for something like
eviction policy. Please take a look here then:
https://apacheignite.readme.io/v1.5/docs/evictions
Please, provide the feedback, if this answer was useful, or not.
Thanks!
public void test() throws Exception {
Ignite ignite = startGrid(0); // some starting util method
CacheConfiguration<Integer, Integer> cfg = new
CacheConfiguration<>();
cfg.setName(CACHE);
cfg.setCacheMode(CacheMode.PARTITIONED);
cfg.setRebalanceMode(CacheRebalanceMode.SYNC);
cfg.setBackups(1);
ignite.getOrCreateCache(cfg);
IgniteCache<Object, Object> cache1 = ignite.cache(null);
IgniteCache<Object, Object> cache2 = cache1.withExpiryPolicy(
new CreatedExpiryPolicy(new Duration(TimeUnit.SECONDS, 1)));
cache1.put(1, 1);
cache1.put(2, 2);
cache2.put(3, 3);
cache2.get(1); // *Does not affect ExpiryPolicy*.
U.sleep(2000);
assert cache1.get(1) == 1;
assert cache2.get(1) == 1; // *not Expired*
assert cache1.get(2) == 2;
assert cache1.get(3) == null; // *Expired*.
}
