> See {{IgniteCacheOffheapManagerImpl.canUpdateOldRow}} - if cache has at least one query entity, in-place updates are not possible. This drastically reduces performance of DML and regular update (cache API) operations. 
> We need to understand whether any explanation of this restriction exists. In any case, in-place updates should be allowed for SQL-enabled caches.
