-----------------------------------
Summary: Broken eviction for OFFHEAP_VALUES cache mode
Key: IGNITE-2509
URL: https://issues.apache.org/jira/browse/IGNITE-2509
Project: Ignite
Issue Type: Bug
Reporter: Denis Magda
Assignee: Vladimir Ershov
In case when {{OFFHEAP_VALUES}} mode is used {{EvictionPolicy}} calculates
values size wrongly which leads to the fact that data is evicted only when
either the limit on number of entries is reached or size of keys is bigger than
max allowed size.
To reproduce set the following cache configuration
{noformat}
FifoEvictionPolicy plc = new FifoEvictionPolicy();
plc.setMaxMemorySize(2 * 1024 * 1024);
cacheCfg.setEvictionPolicy(plc);
cacheCfg.setMemoryMode(CacheMemoryMode.OFFHEAP_VALUES);
cacheCfg.setSwapEnabled(true);
{noformat}
Test that reproduces the issue is attached.
Also attached a patch that fixes the issue. However we should validate that the
fix is full and add additional tests to the test suites.
Finally, {{cache.metrics().getOffHeapAllocatedSize()}} always returns 0 for
this cache mode. Has to be fixed as well.
