[jira] [Created] (IGNITE-3599) Offheap cache memory leaks
Alisher Alimov created IGNITE-3599:
--------------------------------------
Summary: Offheap cache memory leaks
Key: IGNITE-3599
URL: https://issues.apache.org/jira/browse/IGNITE-3599
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 1.6
Reporter: Alisher Alimov
Seems that Offheap cache doesn't free memory resources on IgniteCache#destroy()
Example:
{code}
CacheConfiguration<UUID, UUID> cacheCfg = new CacheConfiguration<>(UUID.randomUUID().toString());
cacheCfg.setBackups(0);
cacheCfg.setCacheMode(CacheMode.PARTITIONED);
cacheCfg.setAtomicityMode(CacheAtomicityMode.ATOMIC);
cacheCfg.setMemoryMode(CacheMemoryMode.OFFHEAP_TIERED);
cacheCfg.setEvictionPolicy(new FifoEvictionPolicy(1));
cacheCfg.setOffHeapMaxMemory(1600000); // ~1 000 000 UUIDs
cacheCfg.setSwapEnabled(false);
for (; ; ) {
IgniteCache<UUID, UUID> cache = analyticsContext.getIgnite().getOrCreateCache(UUID.randomUUID().toString());
for (int j = 0; j < 1000000; j++) {
cache.put(UUID.randomUUID(), UUID.randomUUID());
}
cache.clear();
cache.destroy();
}
{code}
After several iteration for create/fill/destroy operations you could see that using memory for current process is always increasing and seems that off heap cache doesn't free memory resources on IgniteCache#destroy
