>                 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
>            Assignee: Alexandr Kuramshin
>            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.
