> Key: IGNITE-3714
> URL: https://issues.apache.org/jira/browse/IGNITE-3714
> Project: Ignite
> Issue Type: Improvement
> Components: cache, newbie
> Reporter: Alexei Scherbakov
> Fix For: 1.8
>
>
> Default store-by-value semantics of Ignite has bad impact on performance and
> rarely needed.
> We must print the performance hint if some of the caches have copyOnRead
> property set to true (default value).
> It must work both for static and dynamic caches.
> Corresponding thread on dev list:
> http://apache-ignite-developers.2346864.n4.nabble.com/copyOnRead-performance-issues-td10762.html
