-------------------------------------------
Summary: Deserialized value is cached if queries are enabled
Key: IGNITE-4293
URL: https://issues.apache.org/jira/browse/IGNITE-4293
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 1.7
Reporter: Valentin Kulichenko
Priority: Critical
Here is the problematic piece of code in {{IgniteCacheObjectProcessorImpl}}:
{code}
boolean storeVal = ctx.config().isPeerClassLoadingEnabled() ||
GridQueryProcessor.isEnabled(ccfg) ||
!ccfg.isCopyOnRead();
{code}
This flag is set to true if queries are enabled even when binary marshaller is
used (this condition makes sense to other marshallers though). It is then use
in {{BinaryObjectImpl.deserializeValue}}:
{code}
if (coCtx != null && coCtx.storeValue())
obj = obj0;
{code}
As a result, memory consumption doubles.
